Answer to Question #100374 in Physics for Kishwer

Question

What is cyclotron motion.

Answer 1

The cyclotron use the magnetic force on a moving charge to bend moving charges into a semicircular path between accelerations by an applied electric field. The applied electric field accelerates electrons between the "dees" of the magnetic field region. The field is reversed at the cyclotron frequency to accelerate the electrons back across the gap.

A moving charge in a cyclotron will move in a circular path under the influence of a constant magnetic field. If the time to complete one orbit is calculated:

$$T=\frac{2\pi m}{qB}$$

q is charge of the particle, m is the mass of the particle, B is the strength of the magnetic field.
