A wire has a length of 5.00*10-2 m and is used to make a circular coil of one turn. There is a current of 2.20 A in the wire. In the presence of a 1.70 T magnetic field, what is the maximum torque that this coil can experience?

How am I supposed to solve If I can not find the magnetic moment? The equation is NIA and A = area. And I have no clue how to find r= radius. I know pi r^2 is gonna factor in this somehow. Thanks.

you can find the radius with the length, and then the area via the radius

L= (N)(2)(pi)(r)
N in this case being 1
solve for r

then use A= (pi) (r^2)

and substitute A into your NIABsin(phi) equation to find Torque.
