A hollow cylindrical magnet with inner radius a and outer radius b rotates about its axis at an angular frequency m. The magnet has a uniform axial magnetization M = a z ,M 0
• Sliding brush contacts are provided at the inner and outer surfaces as shown in Fig. 7- 14. Assuming that µ r., = 5000 and = 10 (S/m) for the magnet, find
a) H and B in the magnet,
b) open-circuit voltage V 0 ,
c) short-circuit current.
