We show that the principal observational features of power line radiation in the magnetosphere can be described as a van der Pol oscillation subject to incomplete entrainment by an externally injected signal. The nonlinear mechanism is referred to as "periodic pulling" and has been observed in laboratory low‐temperature plasma experiments.
