A flat 174-turn current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 7.05 cm2 and the angle between its magnetic dipole moment and the field is 49.5°. Find the strength of the magnetic field that causes a torque of 1.93 × 10-5 N·m to act on the loop when a current of 2.35 mA flows. T=???
