A wire coil of 25 turns has a cross-sectional area of 10 cm2. The coil is placed in a uniform field of a large magnet with B = 0.17 T. The coil is suddenly rotated 90 o from an orientation parallel to the field to one perpendicular to the field. The time to flip the coil is 0.51 s. What is the magnitude of the average emf produced? What will be the average current produced if the circuit of the coil is closed and the resistance is 55 ohm?

A circular coil enclosing an area of 97 cm2 is made of 201 turns of copper wire. The wire making up the coil has resistance of 6.0Ω
A circular coil enclosing an area of 97 cm2 is made of 201 turns of copper wire. The wire making up the coil has resistance of 6.0Ω, and the ends of the wire are connected to form a closed circuit. Initially, a 1.7 T uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.7 T and points downward through the...
