1. The problem statement, all variables and given/known data A horizontal circular wire loop of radius 0.5 m lies in a plane perpendicular to a uniform magnetic field pointing from above into the plane of the loop, has a magnitude of 0.19 T. If in 0.15 s the wire is reshaped from a circle into a square, but remains in the same plane, what is the magnitude of the average induced emf in the wire during this time? Answer in units of V. The current in the loop during the deformation: 1. does not arise. 2. flows counter-clockwise when viewed from above. 3. flows in a direction that cannot be determined from given information. 4. flows clockwise when viewed from above. 2. Relevant equations Faraday's Law Lenz' Law 3. The attempt at a solution I already solved for the first question, I only included it since it is relevant to the next question. After solving for the emf during the reshaping, I'm uncertain of the current. Since V=IR, I am leaning to thinking there is no current since I am not given any thing related to resistance. Also I'm thinking that a current would only arise if the magnetic field is varying. I'm not sure if the change of magnetic flux will induce a current or not. I'm looking in my textbook and reading as well, but I'm not seeing a definitive answer. Thanks in advance!
