Which risk increases when a pulsed electromagnet exceeds duty-cycle limits?

A)Arcing across coil insulation occurs
B)Eddy currents quench the field
C)Hysteresis loss diminishes output
D)Reflected pulse causes controller error

💡 Explanation

Arcing risk increases due to dielectric breakdown. Excessive heat causes insulation failure, therefore voltage stresses cause ionization, rather than eddy current quenching, because the dielectric breakdown mechanism becomes dominant under pulsed, high-temperature conditions.
