A coil of 125 turns has an area 6.63 × 10-3m2 and has its plane perpendicular to a 75 X 10-3 T magnetic field
A coil of 125 turns has an area 6.63 × 10-3m2 and has its plane perpendicular to a 75 X 10-3 T magnetic field produced by a nearby electromagnet. The current in the electromagnet is turned off leading the magnetic field to disappear and causing an average emf of 0.65 V to be induced in the coll. How much time does it take for the field to disappear in units of seconds? Give your answer as a positive number _______

Imagine that we have a coil consisting of N turns of wire shaped like a circular loop with radius R. We place this coil in a uniform external magnetic field that points perpendicular to the face of the coil. Imagine that the magnitude of this external field is given by the formula B(t) = B_o cos(omega t - phi) where B_o, omega and phi are all constants. Find an expression for the induced emf in the loop as a function...
