Question

Magnetic fields between the parallel plates of a capacitor are due to?

(a) Displacement current

(b) Conduction current

(c) Both conduction and displacement current

(d) Neither conduction nor displacement current

I had been asked this question during an interview.

My doubt stems from Displacement Current in a Dielectric in division Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

The correct option is (a) Displacement current

The explanation: Displacement current is the current which arises due to variations in the field. Change in the field results in the formation of magnetic fields. Hence displacement currents lead to magnetic field between the plates of a capacitor.
