If you wrap a coil of wire around a bar of iron and pass a current, an electromagnet will result. This principle is used in generators where the casing is magnetised and the rotor rotates in the magnetic field inside the casing(the armature), inducing a current in the rotor winding.

∙ 13y agoElectricity is the movement of charges (usually electrons), and any time charged particles move, a magnetic field is created about (around) their path of travel. It's a fundamental tenant of physics. Just like all things with mass have gravity associated with them. Any moving charges (current) will produce a magnetic field about their path of travel because they can not move without creating that magnetic field.

∙ 7y agoThis can only happen if there is relative movement between a moving object and the magnetic field. This will generate a voltage, which in turn may generate a current (if the moving object is a conductor).
The relationships between electricity and magnetism are explained by the Theory of Relativity; I believe they were first described in "On the Electrodynamics of Moving Bodies", by Albert Einstein.

∙ 14y agoIt is not the revolution of electrons, but it is simply the ratio of protons and electrons. electrons are positive ions and protons are negative. So, logically, if there is a higher number of electrons than there is protons, the entire atom becomes positive, and vise versa.

∙ 13y agoFor an electron, which is negatively charged, take your left hand and point your fingers in the direction that the electron is moving. Then, curl your fingers in the direction that the magnetic field is pointing. Point your thumb straight outwards and that is the direction that the electron will bend while traveling through that particular magnetic field. For positively charged particles, you do the same thing, except you use your right hand.

Why do electrons behave like tiny magnets?
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet
If the incident direction of an electron entering a magnetic field is?
If the incident direction of an electron is right, The electron travels a measured distance along the pathÊ prior to exiting the magnetic field.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
What instrument uses a magnetic field to images up to 1000000 times?
an electron microscope :)
What is the left hand rule for conductors?
The left hand rule for conductors says that your fingers will point in the direction of the resulting magnetic field. The magnetic field is produced by the electron flow.
Why do electrons behave like tiny magnets?
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet
If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
If the incident direction of an electron entering a magnetic field is?
If the incident direction of an electron is right, The electron travels a measured distance along the pathÊ prior to exiting the magnetic field.
What is electron effective mass?
it is the mass of an electron in the presence of an electric or magnetic field.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
What will be the Larmor precession frequency of an electron in an atom placed in zero magnetic field?
There is no Larmor precession without magnetic field
What does a electron microscope used to bend electrons?
magnetic field
What does a spinning electron produce?
A magnetic field not a proton :) Hope This Helped!!
What produces an image with the electron microscope?
A magnetic field focuses he electrons
Why photon cannot be deflected by electric and magnetic field?
a photon cannot be deflected by an electric or magnetic field because it has no charge and no magnetic poles like elementary particles such as the electron
What is used to bend electrons in an electron microscope?
Magnetic lenses are used to control the electron beam in an electron microscope. The magnetic field produced by the magnetic lenses deflects the energetic electrons. They are typically called magnetic lenses because they deflect the electron beam like optical lenses deflect light.
What is the magnetic field due to the wire at the location of the electron?
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.
