Main Question or Discussion Point
would be really grateful if someone could help throw some light on this  its probably really simple but I am typing myself up in loops!
I have a piece of wire which is placed in an external AC magnetic field which is varying sinusoidally. The wire is folded to make two rings of radii r1 and r2 with resistances R1 and R2. (see picture below) I have derived an equation for the current in the loop in terms of the emfs E1 and E2 induced in the 2 parts of the loops. I think that this is I = (E1+E2)/(R1+R2)
I want to work out potential difference between the two parts of the loop at their crossing point in terms of the same variables  any ideas on how I would approach this? Thank you very much
