Acircular loop of wire with radius r = 1.0 m is placed in a region where a uniform magnetic field is perpendicular to the plane of the loop. the magnetic field vector points out. the magnitude of the magnetic field is allowed to vary in time according to the equation: b = bo (1-e^-t/t ), for t > _ 0 t = 1.0μs. bo = 0.35 t. suppose the loop has a resistance r = 2.0 x 10^6 ω. a. what is the direction of the induced current / in the loop, clockwise or counterclockwise, for t > _ 0? indicate this direction by drawing an arrow at the wire. b. what is the magnitude of the induced electromotive force at t = 2.0 x 10^-6 seconds?

You estimate the radius of thebig wheel to be 15 {\rm m}, and you use your watch tofind that each loop
