← ScienceWhich field collapse causes transient overvoltage in unshielded inductors?
A)Mutual capacitance charging
B)Rapid magnetic flux change✓
C)Dielectric constant shift
D)Eddy current propagation
💡 Explanation
A rapid change in current flow invokes Faraday's Law of Induction, therefore generating a large voltage spike. With rapid magnetic flux change inducing the voltage peak, rather than effects such as eddy currents and dielectric shifts.
