In inductive circuits, what effect does disconnecting the voltage supply have?

In inductive circuits, disconnecting the voltage supply leads to the inductor temporarily supplying power. Inductors store energy in the magnetic field generated by the current flowing through them. When the voltage supply is disconnected, the current does not stop immediately; instead, the inductor attempts to maintain the current flow due to the energy it has stored.

This phenomenon is governed by Lenz's Law, which states that the direction of induced electromotive force (emf) and current will oppose the change in current that created it. As a result, the inductor will discharge its stored energy by releasing current into the circuit, allowing it to supply power temporarily until the stored energy is depleted. This behavior is a key characteristic of inductive components in electrical circuits, emphasizing the dynamic relationship between current, voltage, and magnetic fields.
