In a region between the planesand , a material that moves in the direction with velocity has the magnetization density cos as shown in Fig. P9.2.2. The regions above and below are constrained so that = 0 there and so that the integral of · ds between and is zero. (In Sec. 9.7, it will be clear that these materials could be the pole faces of a highly permeable magnetic circuit.)
(a) Show that Amp`ere’s law and (9.2.2) are satisfied if throughout the magnetizable layer of material.
(b) A one-turn rectangular coil is located in the 0 plane, one leg running in the direction at (from to ) and another running in the direction at (from to). What is the voltage induced at the terminals of this coil by the motion of the layer?
