The rate at which a charged particle moves in a circular path when it is in a magnetic field.
The gyrofrequency of the electron increased as it moved through the magnetic field.
Gyrofrequency is formed from "gyro-" (from Greek "gyros", meaning circle or rotation) and "frequency" (from Latin "frequentia", meaning the state of being frequent or repeated). The term refers to the frequency of rotation or circular motion.
Think of 'gyro-' meaning 'circle' or 'rotation' and 'frequency' meaning 'repeated occurrence'. This helps you remember that gyrofrequency relates to how often something rotates.
