← ScienceWhich effect arises when rapidly switching a solenoid's magnetic field?
A)Increased inductive voltage spike✓
B)Reduced core saturation point
C)Field emission electron cancellation
D)Enhanced skin effect resistance
💡 Explanation
Switching the solenoid field quickly induces a larger voltage spike because of Faraday's Law of Induction, where the rate of change of magnetic flux directly causes a voltage increase. Therefore, the inductive voltage spike is magnified, rather than other modifications of separate physical properties.
