"WebApr 8, 2024 · In a transformer, the magnetic flux created by the primary coil induces a current in the core. This occurs in order to oppose the charge that produced the magnetic flux (Lenz's Law). The currents flowing in the core are called eddy currents. These currents produce heat, using up energy and so causing inefficiency. " - Can a dc transformer exist why or why not
