Awire is formed into a circle having a diameter of 11.1 cm and is placed in a uniform magnetic field of 2.79 mt. the wire carries a current of 5.00 a. find the maximum torque on the wire.

Maximum torque on the wire is

Explanation:

It is given that,

Diameter of the wire, d = 11.1 cm = 0.111 m

Radius of wire, r = 0.0555 m

Magnetic field,

Current, I = 5 A

We need to find the maximum torque on the wire. Torque is given by :

Torque is maximum when,

or

So, the maximum toque on the wire is . Hence, this is the required solution.
