An electron enters with a velocity v = v0i into a cubical region in which there are uniform electric and magnetic fields. The orbit of the electron is found to spiral down inside the cube in the plane parallel to the x-y plane. Suggest a configuration of fields E and B that can lead to it.
The spiral route is formed by the fields E and B in their current configuration.
A current-carrying loop consists of 3 identical quarter circles of radius R, lying in the positive quadrants of the x-y, y-z, and z-x planes with their centres at the origin, joined together. Find the direction and magnitude of B at the origin.

Describe the motion of a charged particle in a cyclotron if the frequency of the radio frequency (rf) field were doubled.
The time period of the radio frequency is halved when the frequency is doubled, resulting in a half revolution of the charges.
