Why do magnetic fields cause electrons to move?

Orbital motion referred to the motion of an electron around the nucleus of the atom. Since a charged particle was moving, a magnetic field was created. But electrons (and protons and other particles) also appeared to be spinning around their centers, creating yet another magnetic field.

Can you move an electron at rest with a magnet?

An electron at rest in a magnetic field experiences no force, so cannot be set in motion by the magnetic field. If it were placed at rest in an electric field, it will accelerate under the electrostatic force.

Can a magnetic field speed up an electron?

The magnetic force will not change the speed of a moving electron because the magnetic force is always perpendicular to the velocity. A moving electron in a uniform magnetic field will undergo uniform circular motion.

How can a magnetic field move?

The magnetic field direction goes from the north pole to the south pole of the magnet, and observation tells us that north poles are attracted to south poles once one has many magnets. Thus a magnet will move another magnet if brought to proximity according to the rule, same poles repel, different poles attract.

Can electrons move?

Electrons do not move along a wire like cars on a highway. Actually, Any conductor (thing that electricity can go through) is made of atoms. If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom.

Does magnetic force attract electrons?

Magnetic fields can be used to make electricity Moving magnetic fields pull and push electrons. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.

Can a magnetic field trap electrons?

The transverse motion of electrons – their gyration in the magnetic field – causes synchrotron emission at high harmonics of the gyrofrequency (to be dis- cussed in Section 8.1). Trapped electrons are important sources for intense coherent radio emission.

Which way does an electron move in a magnetic field?

The direction of the force acting on the electron is the direction the palm of the left hand faces. The direction of the magnetic field, the direction of the moving charge, and the direction of the force on the particle are all perpendicular to each other.
