Hi everyone! I'm trying to work out a physics problem using Lenz's Law, but I'm having trouble with the Right Hand rule, which as I understand is supposed to be used to solve the problem.
1. Basically, there are 2 copper wire loops, Loop A and Loop B. They are lying flat on the table. There is a magnetic field, B, inducing current, I, in both loops. However, for Loop A magnetic field lines point downward and for Loop B magnetic field lines point upward.
The question is:
Determine the direction of the induced current in (a) Loop A and (b) Loop B. Specify the direction of each induced current to be clockwise or counterclockwise when viewed from above the table. Provide a reason for each answer.
2. No equations needed
3. It seems to be pretty straightforward, since Lenz's Law says that current will try to oppose the magnetic field. So I tried the right-hand rule: thumb points in direction of the current, and fingers curl in direction of magnetic field... But I'm confusing myself, since it's the current that's supposed to curl arround, not the magnetic field The magnetic field just goes up or down...
Please help! I just don't get it :(
Thanks.
