← ScienceWhich mechanism causes parasitic currents in transformer laminations subjected to alternating electromagnetic fields?
A)Lenz's Law induction causes eddy currents✓
B)Dielectric breakdown causes corona discharge
C)Magnetic hysteresis causes domain alignment
D)Skin effect causes resistive heating
💡 Explanation
Eddy currents arise due to Faraday's law of induction; oscillating magnetic fields induce a circulating current within the conductive lamination. Therefore, significant heat loss occurs due to eddy current losses rather than corona discharge from dielectric breakdown concerns.
