A large block of a newly found conducting material has current, I, running through it. a. What can be concluded about the electric and magnetic fields inside of the block? b. This new material is found to always have B = 0 inside of its structure. Explain why the current flowing through it must be confined to the surface. c. If a small permanent magnet of mass, M, were introduced in the region above this block, it would levitate due to induced currents in the block. Using the method of images and taking the permanent magnet to be a perfect dipole, m, pointing perpendicularly away from the plane of the black, determine the height, z, that the permanent magnet will levitate above the block. d. If the same small permanent magnet were free to rotate, what new orientation would it come to and at what new height would it levitate?
