A uniform magnetic field of magnitude B = 0.170 T pointing out of the page exists in a region where there is a wire wrapped N times around in a circle of radius r = 1.70 cm and then connected back onto itself. The wire assembly is moved completely out of the field (by the person in the figure, but we know people aren't that small-so it must be a Gremlin) during a time interval At = 34.0 ms. The average induced emf has a magnitude ɛ = 22.7 mV. a. Find the number of wraps N in the wire loop. b. Is the induced current in the wire loop clockwise or counterclockwise? Explain!
