cyclotron resonance

Cyclotron resonance occurs when charged particles, like electrons, move in a magnetic field and are subjected to a matching electromagnetic wave frequency. When the wave's frequency aligns with the particles' natural circular motion (their gyrofrequency), they absorb energy efficiently, increasing their motion. This resonance condition allows scientists to study properties of materials and plasmas by observing how particles respond to specific frequencies, providing insight into magnetic fields and particle behaviors in various environments.
