Electron cyclotron resonance (ECR) is a phenomenon that occurs when charged particles, such as electrons, move in a magnetic field and absorb energy from an electromagnetic wave at a specific frequency. This frequency corresponds to the cyclotron frequency of the particles, which is determined by the strength of the magnetic field and the mass and charge of the electrons.
