1. A 15 turn coil with radius 3.0cm is oriented so that the normal to the coil is at 30 to a field of 2.88x10-4 T. If the coil is rotated so that its normal is at 80 to the field in 0.25s, what emf is induced in the loop? 2. A step up transformer has No=25 and N=500. You want to produce 4800V with a current of 28mA on the secondary. What voltage and current should you use on the primary?
