Which outcome occurs from domain realignment in transformers?

A)Increased hysteresis energy loss
B)Enhanced magnetic field confinement
C)Reduced eddy current generation
D)Improved dielectric breakdown strength

💡 Explanation

Increased hysteresis energy loss happens because the ferromagnetic core of a transformer dissipates energy as heat due to the constant realignment of magnetic domains during alternating magnetization. Therefore, hysteresis energy loss increases, rather than field confinement because domains switch rather than align perfectly.
