Which outcome occurs when eddy currents saturate laminated transformer cores?

A)Increased hysteresis power loss
B)Reduced dielectric breakdown voltage
C)Elevated primary winding inductance
D)Decreased circulating current magnitude

💡 Explanation

Increased hysteresis power loss results because the magnetic domains cannot continually align to minimise energy via domain wall motion, because the eddy currents induce opposing dynamic magnetic fields; therefore hysteresis losses increase, rather than reduced dielectric breakdown.
