1. The problem statement, all variables and given/known data Two parralel wires are 8 cm apart. The magnetic field halfway between them is 300 uT. What equal currents must be in the wires? Consider parralel and antiparralel currents 2. Relevant equations I use Ia=Ib B = (u*i) / (2*Pi*distance) where distance = 0.04 m (0.08m divided by two since it is halfway) then I solve for I, I get 60 Amperes, the answers is 30 amperes What to do?
