NEET 2025 Physics Displacement Current MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is:
A
zero at all places
B
constant between the plates and zero outside the plates
C
non-zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the plates
D
zero between the plates and non-zero outside
Correct Answer
Option C
Detailed Explanation
The displacement current creates a magnetic field similar to a real current. The field is non-zero everywhere and is maximum at the cylindrical surface connecting the edges of the plates.
