A 52.5-turn circular coil of radius 5.35 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0.455 T. If the coil carries a current of 25.3 mA, find the magnitude of the maximum possible torque exerted on the coil.

Why is there a magnetic field even when there is no current?
