NEET Physics Magnetic Force on Current Assertion Reason Question
Assertion (A): The magnetic force on a current-carrying wire is zero if the wire is aligned parallel to the magnetic field. | Reason (R): The magnetic force depends on the sine of the angle between the current direction and the magnetic field.
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, but R is true.
Correct Answer
Detailed Explanation
The magnetic force is zero when the wire is parallel to the magnetic field because the angle is 0 degrees, making sin(0) = 0.
