Answer to Question #27193 in Electricity and Magnetism for miguel

Question

The inner radius of a toroid is 10 cm, the outer radius is 14 cm, and the height is 4 cm. A uniformly wound coil carries a current of 0.5 A. If the magnetic field intensity at the mean radius is 79.578 A/m, detennine the number of turns in the coil. Calculate the energy stored in the magnetic field if the permeability of the core is 500.
