Examples of circular motion include : an artificial satellite orbiting the Earth at constant height, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a mechanism.

The cyclotron frequency is also useful in non-uniform magnetic fields, in which ( assuming slow variation of magnitude of the magnetic field ) the movement is approximately helical-in the direction parallel to the magnetic field, the motion is uniform, whereas in the plane perpendicular to the magnetic field the movement is, as previously, circular.

An electron in a static and uniform magnetic field will move in a circle due to the Lorentz force then if a electromagnetic wave of the right frequency ( the same as the electrons circular orbit frequency ) then the electron would gain energy is their anyway for the electrons energy to be directly turned into electricity ?
