Current Coupled Coils

W.1.6 Current Coupled Coils

Two solenoid coils connected by wires are arranged so that magnets on springs oscillate in them. When one magnet is set oscillating, the induced current causes the other to oscillate also. Note that the oscillations are coupled through the velocity term rather than the amplitude term as in coupled pendula.
