circular conducting ring
A circular conducting ring with radius r0=0.0420 m lies in the xy-plane in a region of uniform magnetic field 
. In thisexpression, t0=0.0100 s and is constant, t is time, 
is the unit vector in the+z-direction, and 
=0.0800 T is constant. At points a and b (see the figure ) there is a small gap in the ring with wires leading to an external circuit of resistanceR=12.0 Ω. There is no magnetic field at the location of the external circuit.
a) Because of the internal resistance of the ring, the current through 
at thetime given in part B is only 
. Determinethe internal resistance of the ring.
b) Determine the emf in the ring at a time 
.
c) Determine the time at which the current through reverses its direction.

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...
