← ScienceWhich risk increases when a ferromagnetic core saturates?
A)Transformer core eddy current losses✓
B)Permanent magnet domain wall pinning
C)Superconductor Meissner effect attenuation
D)Resistor thermal runaway susceptibility
💡 Explanation
Transformer action depends on induced EMF. When ferromagnetic core saturates, magnetic permeability plummets, decreasing inductance, because any further increase in current does not increase the magnetic field -- therefore eddy current loss accelerates exponentially, rather than efficient AC energy transfer, under normal operating conditions.
