1. The problem statement, all variables and given/known data Two long parallel wires are separated by 4.0mm. The current in one of the wires is twice the other current. If the magnitude if the force on a 2.0m length of one of the wires is equal to 7.0μN, what is the greater of the two currents? 2. Relevant equations F(b)=μ*I(1)*I(2)*l/2∏a 3. The attempt at a solution I'm afraid I oversimplified my approach to this problem. I plugged the known values into the equation above and solved for I. I was then going to multiply that value by two. I am certain that is wrong, and that I am missing an important concept with regards to the problem. A shove in the right direction would be much appreciated!
