Find the torque of a loop with magnetic moment 12.5 and magnetic flux

1.	Find the torque of a loop with magnetic moment 12.5 and magnetic flux density 7.65 units is(a) 95.625(b) 65.925(c) 56.525(d) 65.235I had been asked this question in semester exam.This intriguing question originated from Magnetic Dipole in chapter Magnetic Forces and Materials of Electromagnetic Theory
Answer» Right choice is (a) 95.625 Explanation: The TORQUE is DEFINED as the product of the magnetic MOMENT and the magnetic flux DENSITY given by T = MB, where M = 12.5 and B = 7.65. Thus we get T = 12.5 X 7.65 = 95.625 units.
