Assume the magnitude of the magnetic field outside a sphere of radius R is B= B0(R/r)2, where B0 is a constant. (a) Determine the total energy stored in the magnetic field outside the sphere. (b) Evaluate your result from part (a) for B0 = 5.00 × 10-5 T and R = 6.00 × 106 m, values appropriate for the Earth’s magnetic field.
