Your physics professor is doing a demo to demonstrate Faraday’s law. He usesa 5m long wire of 10 Ohms total resistance, and he shapes it as a perfect square.Your professor places the loop in a plane perpendicular to a 2 Tesla uniformmagnetic field pointing from above into the plane of the loop. Then yourprofessor re-shaped the wire in five seconds from a square into a perfect circle.The new loop remains in the same plane.a. What is the magnitude of the average induced emf in the wire during thistime?b. Find the direction, and average magnitude of the current in the loopduring the deformation? Explain your reasoning.
