NEET Physics Ampere's Law Assertion Reason Question
Assertion (A): Ampere's law can be applied to find the magnetic field inside a current-carrying wire.
Reason (R): The magnetic field inside the wire is directly proportional to the radial distance from the center of the wire.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Ampere's law is applicable inside the wire where B is proportional to r, as derived using the uniform current distribution, supporting both A and R.
