Problem: Calculate how much current is required to make the field at the center of a current loop comparable to the magnetic field near one of the poles of a permanent magnet. The field nears to be a typical bar magnet is about B bar =2 T. A single circular wire loop of radius R = 0.50 cm carrying a current I. What value of I is needed to produce a field equal to B bar at the center of the loop?

I need expert help for the above problem.
