Aloop of wire with cross-sectional area 1×10^−3 m^2 lays centered in the xy -plane. the wire carries a uniform current of 180a running counter-clockwise. what is the magnitude of the magnetic moment of the current loop?

Explanation:

Given that,

Area of the loop,

Current flowing in the wire, I = 180 A

We need to find the magnetic moment of the current loop. It is given by :

So, the magnetic moment of the current loop is . Hence, this is the required solution.
