Asquare loop of wire with sides of length l and carrying a conventional current i lies in the yz-plane with its center at the origin. a. what is the magnitude of the magnetic field due to this loop at a location x on the x-axis?
b. what is the approximate equation for the magnitude of the magnetic field at a location x that is much greater than l , in terms of the magnetic moment of the loop?
c. is the result of part (b) consistent with our previously derived result for the magnetic field of a magnetic dipole?
provide explaination.
