A 50.0-turn circular coil of radius 5.00 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0.500 T. If the coil carries a current of 25.0 mA, find the magnitude of the maximum possible torque exerted on the coil.

The maximum torque exerted on the coil is 0.0049 Nm.

The given parameters;

The maximum torque exerted on the coil is calculated as follows;

where;

Thus, the maximum torque exerted on the coil is 0.0049 Nm.

The maximum torque in the coil is .

Explanation:

Given that,

Number of turns in the circular coil, N = 50

Radius of coil, r = 5 cm

Magnetic field, B = 0.5 T

Current in coil, I = 25 mA

We need to find the magnitude of the maximum possible torque exerted on the coil. The magnetic torque is given by :

For maximum torque,

So, the maximum torque in the coil is .
