How does an electron behave in a magnetic field?

Answer 1

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.

Answer 2

An electron in a magnetic field experiences a force perpendicular to its velocity called the Lorentz force. This force causes the electron to move in a circular or helical path depending on its initial velocity and the strength of the magnetic field. The electron's trajectory can be described by the Lorentz force equation and is the basis for applications like particle accelerators and MRI machines.

Answer 3

Electricity 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.

Answer 4

This 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.

Answer 5

It 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.

Answer 6

For 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.

Answer 7

They are paired by pairing with other electrons

any moving charge creates a magnetic field

Answer 8

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

Answer 9

a magnetic field is produced by moving charged particles. an electric field contains moving charged particles, thus it creates a magnetic field.

Answer 10

The electron - or any other charged object - will have a magnetic field if it moves. The electric charge will be the same, whether it moves or not.
