← ScienceWhich mechanism prevents complete saturation in ferromagnetic cores affected by high frequency signals?
A)Magnetic domain wall pinning
B)Eddy current induced opposition✓
C)Magnetostriction induced demagnetization
D)Thermal agitation randomization
💡 Explanation
Eddy currents oppose the external magnetic field because Lenz's law induces circulating currents that generate a counter-field; therefore, the core resists full saturation rather than responding immediately to rapidly changing external fields due to domain alignment.
