If a metal ring is places near a solenoid, what is the direction of the induced current in the ring for the following cases a. At the instant the swithc in the circuit containing the solenoid is thrown closed. b. After the switch has been closed for several seconds. c. At the instant the switch is thrown open. I think that I have to do the right hand rule for this problem, but my problem is that I have a hard time understanding the right hand rule, so is there any way of finding the direction for something other than the right hand rule? How about the dot product? For instance, what does "into the page" and "out of the page" mean?
