Homework Statement
(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

(C) the wire A is raised out of the plane of the paper.
Homework Equations
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.
