NEET Physics Maxwell's Equations MCQ Question
Consider a parallel plate capacitor with a time-dependent current flowing through it. Describe a diagram in which (a) shows a loop of radius r to determine the magnetic field at a point P on the loop, and (b) shows a pot-shaped surface passing through the interior between the capacitor plates with the loop as its rim. Which law is used to calculate the magnetic field in this scenario, considering the role of displacement current?
Ampere-Maxwell Law
Gauss's Law for Electricity
Faraday's Law
Gauss's Law for Magnetism
Correct Answer
Detailed Explanation
The Ampere-Maxwell Law accounts for both conduction current and displacement current, which is essential for calculating the magnetic field in the scenario described with a parallel plate capacitor.
