the 2.0 cm diameter coil has 25 turns and has a current flowing through it of 5 A. The magnetic field strength is .4 T. The angle shown in the diagram is 30 degrees above the horizontal. if the coil rotates at 2 pi for one revolution, in 1 second how long does this take? What is the emf due to the change in flux? (this is calcuatlte with the change in 30 to 90 degrees).
