Coupled circuits can be analyzed by representing them as equivalent circuits. The equivalent circuit for a magnetically coupled circuit contains mutual inductance terms that account for the magnetic coupling between coils. The equivalent circuit equations relate the voltages across each inductor to the currents through each inductor, the resistances, and the mutual inductance. As an example, a magnetic circuit is shown and its equivalent conductively coupled circuit is to be drawn to calculate the current supplied by the voltage source.
