If I have a top view of two circular coils of conducting wire lying on a flat surface, what is the direciton of induced current that appears in the smaller coil when the switch in the larger coil is closed? I'm trying to figure out: 1.) which direction the induced current would flow through the smaller coil 2.) how long it would flow: forever, or only for a short time. I've attached a picture of the wires for clarification. I'm not sure how to solve this. I know that induced current in a loop occurs only when the magnetic field through that loop changes. I'm assuming that when the switch is closed a current will run counterclockwise around the larger loop, but I don't know if this is a valid assumption, or what that does for the smaller loop. Can soemone help please? Thank you.
