Wire loop parallel to and above an infinite plane of iron

  • #1

Homework Statement



A wire Loop R with a current I=10A running through it, is distance d above an infinite plane of iron with mu=5mu_0 R=2d. Find the force on the loop

Homework Equations



I would assume you could use image currents in the plane of iron to solve this

The Attempt at a Solution



I have no idea where to start: I drew an "image current loop" a distance d BELOW the plane, labeled I', and now I need to get I in terms of I'? How am I supposed to do that?

Thanks in advance

Or is there another way of doing this that I'm somehow missing?
