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.
