Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). Mark the correct choice as: |
Assertion [A]: The net magnetic force on a current carrying loop in a uniform magnetic field is zero but torque may or may not be zero. |
Reason (R): Torque on a current carrying coil in a magnetic field is given by \[\overrightarrow{\tau }=nl(\overrightarrow{A}\times \overrightarrow{B})\]. |
