Do paired electrons create magnetic fields?
No - magnetism is created by moving electric charges.
What does magnets have in them?
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 electrons have aligned themselves so their spins are parallel. (More moving electrons - even if they are just spinning).The commonest members of this group are iron and nickel materials, though a dozen or so materials may aid the strength of the magnet.Electromagnetic machines are such things as electric generators and motors, relays and solenoids.The Earth has a magnetic field, generated we believe by electric currents flowing in the mantle, roughly parallel to the Equator.
How is earth's magnetic field like the magnetic field of a natural magnet?
A magnetic field is induced by the movement of electrons.In an electromagnet, the flow of current ensures this.In a permanent magnet; there is a grouping of 'magnetic domains' in which the alignment of the spin of a group of electrons is similar; will produce a permanent magnetic field. In this case the movement of the electrons is their property of 'spin'.The Earth's magnetic field is generated by the net sum of electric currents generated in the mantle, produced by movement of the hot materials.Note, that the 'Curie Point' (discovered by the Curies), is a temperature above which a magnet may not hold its magnetism. The thermal disorder takes precedence over the previous alignment of the electron spins.Because of the Curie Point, there is no possibility of a permanent magnet existing in the interior of the Earth and causing the Earth's magnetic field.The Earth's magnetic field varies with time, and has reversed its polarity on several occasions. It also varies somewhat with the effects of the charged 'solar wind'. When there is a 'mass coronal ejection' and if it happens to face the Earth at that time, the Earth's magnetic field will be severely disrupted.In the 1859 'Carrington Event' such a storm caused much damage to the electric circuits of the day. Such an event today could well essentially destroy modern civilization.One such Coronal Mass Ejection occurred on July 2012, but fortunately was pointed away from Earth.
What holds earth together Think of the earth as the nucleus of an atom. And around the earth are electrons. These electrons create magnetic energy that holds earth together.?
Electrons produce a magnetic force that holds earth together and trees
Does the earth's magnetic field give information on the earth's interior composition?
The earth has electric currents in its structure, that create magnetic fields.
What is a grouping of electrons and ions that react collectively to forces exerted by electric and magnetic fields?
mad black guy on crack about to steel from the chinese store!
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
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.
Do paired electrons create magnetic fields?
No - magnetism is created by moving electric charges.
Why there exists magnetic Field when there is no magnetic charges practically?
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].
What happens when an electric field is placed inside a magnetic field?
Electricity is formed (electrons move )
What does magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
What is magnetism produced by?
Magnetism is produced by the alignment and movement of electric charges, specifically electrons, within a material. In some materials, such as iron, nickel, and cobalt, the alignment of these charges creates a net magnetic field that can attract or repel other magnetic materials.
Compare magnetic circuit and electric corcuit?
Manetic circuits are made of one or more closed loops containing magnetic fluxes. Electronic circuits are a flow of electric charge by moving electrons in a wire.
Does a magnet have electrons?
An electron is a charged particle and as such it is surrounded by an electric field. A magnet is in general not charged so it will not form an electric field. It will, however, form a magnetic field. In case your question is what an electric field is made of, then the answer is (virtual) photons, which are the mediators for the electromagnetic force.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
