How moving magnetic field cause electrons to move?
Yes. The best example is the electromagnet. A constant current of electrons flow through a copper coil. The arrangement of the coil makes that the magnetic field generated by the moving charges add up to an stronger magnetic field. As a result, the magnetic field is strong enough to attract iron object. In this example, the moving charges are the electrons.
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
They are paired by pairing with other electrons any moving charge creates a magnetic field
Electromagetism is a unified force. A magnetic field that is moving relative to a wire will cause electrons within the wire to move. Less common is a moving wire in a stationary magnetic field, but the relative movement between the wire and magnetic field induces the same movement of the electrons within the wire. This action of moving the electrons in a wire (or Armature) produces the electric current that may then be used to… Read More
All magnetic fields are caused by the movement of electrons. No moving electrons = no magnetic field. And if we have many electrons moving, then the magnetic field will accordingly be greater. 12 amp has 12 times the number of electrons flowing as does 1 amp.
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other. Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one… Read More
answ2. The movement of electrons will produce a magnetic field. Whether by the spin of the electron or its movement. All magnetic fields are produced by moving electrons. Even those on the Sun where it is too hot for magnetic materials. When you cause a current flow through a wire, the flow of electrons will induce a magnetic field. Adding an iron core within the coil, will make the magnetic field stronger. This is then… Read More
The moving electrons - whether in a magnetic field or not - ARE an electric current, since an electric current is (roughly speaking) defined as the movement of charged particles.
Any permanent magnet, irrespective of shape, has been treated so as to align groups of electrons to spin in the same direction. Normally, the electrons will have spin in random directions. By aligning the electron spins, they have now created an aligned magnetic field. All magnetic fields have the flow or the spin of electrons as their cause. No moving electrons - no magnetic field.
Moving electrons always have a magnetic field around them
The term "magnetic field" refers to the strength of magnetism surrounding electrical currents or magnetic matter. Electrons play a large part in the process of magnetism, as moving electrons will generate a magnetic field.
when any moving charge enters a magnetic field this induces an EMF, this is in volts, and so when an electron moves through a magnetic field it will induce and emf
Electrons have a charge. Any moving charge creates an electric field, e.g. electricity moving through a wire causes a magnetic field around the wire, or the earth rotating creates a magnetic field which causes a compass to point north. Similarly all electrons have a spin factor. similar to the earth rotating, the spin of electrons create a magnetic field around the electron.
A good question. When an electron is moved, it will generate a magnetic force. In a permanent magnet, there are a 'magnetic domains' in which a number of electrons have similar spin direction. In an electromagnet, there are, by definition, a number of electrons moving in the same direction. If you do not have a moving electron, you do not have a magnetic field! From this statement, you may deduce that the amazing magnetic loops… Read More
Why does moving electrons In a wire or coil create magnetic field especially that circular one around a single wire And is there magnetic field if we could shoot electrons as beam like in CRT?
Anytime any electrical charge moves a magnetic field is created. It does not matter if the moving charge is in a wire or in a vacuum. It does not matter if it is a single wire or a coil of wire. As soon as a charge moves a magnetic field is created.
Yes, they do.
No. Static electricity will not produce a magnetic field. A magnetic field is basically caused by moving charges, i.e., by a current, by electrons orbiting their atom, etc.
This depends if they are charged or neutral and if they are moving or not. A: If they are not moving then nothing usually and if they are neutral nothing. B: If they are charged and moving then they begin to accelerate in the direction of the magnetic field. C: If the object is a magnetic object for instance Iron that shares its electrons metallically then it will feel a acceleration in the direction of… Read More
Any atom with unpaired electrons in it's orbital exhibits paramagnetism, that is that it will be attracted into an inducing magnetic field. Phosphorous has 15 electrons: 1s>2e-(all paired) 2s>2e- 2p>6e-(all paired) 3s>2e-(these two are paired) 3p>3e-(note that these are the unpaired electrons that cause it to be paramagnetic) All this is because a moving negative charge produces a magnetic field if there are two electrons in the same orbital they always spin in opposite directions… Read More
A moving electric charge will produce a magnetic field. A moving electric charge will produce a magnetic field. A moving electric charge will produce a magnetic field. A moving electric charge will produce a magnetic field.
the basic difference is the origin point. the magnetic field originates due to magnetic dipole and the electric field originates due to the charged particles. An electric field surrounds electrically charged particles and time-varying magnetic fields. It can be said Electric fields are generated around particles that bear electric charge or where magnetic field is changing with time Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents… Read More
A magnetic field is produced by any charged particle in motion. It is a fundamental law of nature (as expressed by the electromagnetic force) that a magnetic field will form around any moving charge. We usually think of moving electrons as creating a magnetic field, and this is absolutely correct, but any moving charge can create a magnetic field. As for what magnetism is, this question has already been answered, and link is provided below… Read More
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
The electron has a permanent magnetic field at rest, it clearly has a magnetic field because it is always moving and a moving charge has a magnetic field. In the same manner, the proton also has a natural and permanent electromagnetic field since it has a Magnetic Moment.The electron and the proton are in continuous motion, both on their own axes and around each other.This is the reason , why electrons and protons are deflected… Read More
The electrons moving through the current are atomically magnetic, and create a magnetic field around all currents. To find this magnetic field you could use the left hand rule (where you point your thumb in the direction of the current and your fingers curling represents the magnetic field movement).
No. Magnetic field arises due to a specific arrangement of electrons inside a substance. Hmm, I'd guess Yes. When there is electricity, there is a magnetic filed. Whenever an electron moves, not only does its electric field move, but also a magnetic field may be appreciated (if you are not moving with the electric field). OK, so gravity doesn't have a magnetic field.
A moving charge produces a current, or rather a time varying electric. A moving electron alone actually does not produce a magnetic field.
That is a very simple answer. Electricity! Moving electrons constitute a current, and a current is surrounded by circular loops of magnetic field.
This is my opinion. It should not be taken as scientific fact, unless proved so. The electrical charge can not exist with out corresponding magnetic field and vice verse. They must go hand in hand.
If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
No. Only an electron moving relative to the field experiences a force.
A moving current of electrons produces a magnetic field. The electric force and magnetic force are one in the same: The electromagnetic force.
Magnets depend absolutely on moving electric charges. In the case of permanent magnets, the spin of the electrons is the source of this charge. Many electrons similarly aligned produce the magnetic field. Otherwise with an electromagnet, the electric current flows in a coil of wire, thus creating a magnetic field within the coil. These principles are used to generate electric power, by moving a coil of wire through a magnetic field. This will induce a… Read More
A magnetic field is induced by moving electric charges, either by an actual electric current, or the way that electrons (charged particles) spin around the nucleus [in the case of magnetic materials becoming magnetized].
It is cause when a conductor has been exposed to moving magnetic field due to the motion of the field source.
Which is true electric current running along a wire can be used to produce magnetic force or moving electrons through a magnetic field can produce an electric current?
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
Not around... moving THROUGH a magnetic field forces electrons to flow through a wire.
To understand this explanation you must first know: 1)magnetic fields exert force on moving electric charges 2)moving electric charges create magnetic fields The spin of the electrons in a ferromagnet are initially unaligned, the electrons in each atom of the ferromagnet are spinning in any which direction each of them please. Magnetic fields can be created by electric charges in motion. Just like you get a magnetic field from running current through a wire. When… Read More

A magnetic field is caused by the movement of electrons. If there are no moving electrons, there is no magnetic field. Even in a permanent magnet, the electrons are spinning. And there is an unbalance between the spin directions. We arbitrarily assign north and south to the poles of a magnet. A fundamental law of magnetism is 'Like poles repel, unlike poles attract'. Hope that is what you want.
An object that creates a magnetic field will exert a magnetic force an a moving, charged particle. How it does this is part of the fundamental nature of the universe.
Motion of electrons inside the coil by variation of applied magnetic field.(more precisely magnetic flux).Varying magnetic field applies lorentz force on the electrons which aligns them in a particular direction which causes a net current in the circuit. SAMITA
When a charged particle moves through a magnetic field it experiences a force from that field. When an electrical conductor moves through a magnetic field the electrons, which are negatively charged, being moving, creating an electric current.
The answer is: Yes, it does. And the reason is this: In a magnet the electrons in the atoms are spinning in the same direction, which gives a magnet its magnetic domain-north or south-and creates a magnetic field. If the electrons are spinning every which way, the domains are scattered and the magnet is not magnetized. Dropping, hitting, or heating a magnet will disturb the magnetic field-the spin of the electrons goes out of alignment… Read More
Permanent magnets have a magnetic field around them. This field is an "area" of force, and the force is derived directly from the uniform motion of a large number of electrons in the ferromagnetic material. Moving electrons generate a tiny magnetic field around their path of travel, and this is the basis of the magnetic force. The "blocks" of atoms that have uniformly moving electrons are called magnetic domains. The aligned domains allow an "over… Read More
Microwaves in a microwave oven are produced by electrons circling in a magnetic field at a frequency of 2.4GHz. what is the magnetic field strength?
A cavity magnetron is used to produce microwaves in a microwave oven. (See related inks.) Though this involves a magnetic field and an oscillating electron beam, the electrons are not moving in a circle at the cyclotron resonance and this is not the basic mode of operation.
A current passing through a wire creates a magnetic field around the wire, due to effects of special relativity (the electrons are moving FAST). Alternatively, a changing magnetic field (such as created by a moving magnet) induces electric current in a nearby wire. Faraday's Law describes this behavior.
When there are moving electrons, there is a magnetic field. No moving electrons = no magnetic field. We can make an electromagnet by passing an electric current (= moving electrons) through a wire coil. And that field may be strengthened further by placing a soft iron core inside the coil. There are also permanent magnets, with which you're already familiar - a compass, a fridge magnet and so on. These are materials in which the… Read More
Magnetic field is produced by varying electic field. It is a vector quantity. It originates from North pole and passes to south pole and it is a closed loop. Magnetic forces gives information about charge carriers in a material through Hall effect answ2. A magnetic field may be a fixed one - it does not need to vary. Consider a permanent magnet. All magnetic fields are caused by the movement of electrons. No moving electrons… Read More
a magnetic field is produced by moving charged particles. an electric field contains moving charged particles, thus it creates a magnetic field.
By moving it through a magnetic field, and/or by causing a moving or changing magnetic field to interact with it.
