1. The problem statement, all variables and given/known data (See image) a closed circular wire A lies in the plane of the wire B in the circuit. Deduce the direction. Of the induced current in A when (A) the switch is closed (B) the switch is opened (C) the wire A is raised out of the plane of the paper. 2. Relevant equations 3. The attempt at a solution (A)I used lenz's law and I think that as the field from the circuit will be pushing Down on the wire it will produce a revolving field which opposes the circuit field. I think it is anticlockwise. (B) no idea (C) trick question, no change in flux so no current.
