← ScienceWhich mechanism causes hysteresis in ferromagnetic core inductors?
A)Domain wall Barkhausen jumps✓
B)Eddy current self inductance
C)Skin effect resistivity increase
D)Capacitive dielectric polarization
💡 Explanation
The inductor exhibits hysteresis because the domain wall Barkhausen jumps resist the magnetic field change. This energy dissipates as heat, therefore it lags and is irreversible, rather than being instantly reversible due to inductance alone.
