1. The problem statement, all variables and given/known data So, I have a problem where I have two concentric current loops. The final statement in the problem is: "estimate the mutual inductance between loops if the positive direction of current is the same for both loops." If the currents of the loops are the same direction, how does this change the problem? I have already found the mutual inductance induced by loop 2 on loop 1, and vice versa. How do I finish the problem? Thanks for the help!
