Magnetic Effects Of Current Question 384

Question: A rectangular coil $ ( Dimension5cm\times 2.5cm ) $ with 100 turns, carrying a current of 3 A in the clock-wise direction, is kept centered at the origin and in the X - Z plane. A magnetic field of 1 T is applied along X - axis. If the coil is tilted through $ 45{}^\circ $ about Z - axis, then the torque (in Nm) on the coil is:

Solution:

Answer: 0.27
