An alternating current (AC) signal with significant harmonic content passes through a poorly shielded inductor. Which effect dominates on the inductor's core due to non-sinusoidal current?

💡 Explanation

Because the AC signal contains harmonics (non-sinusoidal components), the magnetic field in the inductor core varies non-uniformly during each cycle; this leads to increased energy dissipation via the hysteresis mechanism. Therefore, hysteresis losses are greater, rather than reduced core saturation or minimized eddy currents, which would require specific core materials or signal characteristics.
