Physics-Magnetic Force on Current

NEET Physics Magnetic Force on Current Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 12

Assertion (A): A straight conductor carrying current in a uniform magnetic field experiences a force perpendicular to the direction of the current. | Reason (R): The force on a current-carrying wire in a magnetic field is given by F = I l × B, where the direction of l is given by the direction of the current.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option A

Detailed Explanation

According to the NCERT context, the force on a straight conductor in a magnetic field is given by F = I l × B, which is perpendicular to the direction of current, validating both the assertion and reason.
