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.
