A rectangular coil of sides 12 cm and 8 cm having 1000 turns and carrying a current of 250 mA is placed in a uniform magnetic field of 0.25 tesla directed along positive x-axis. (i) What is the maximum torque the coil can expereince and in which direction? (ii) For which orientation of the coil is the torque zero?

Text Solution

Verified by Experts

0.6 N.m when x-axis lies in the plane of the coil, zero when x-axis is perpendicular to the plane of the coil
