1. The problem statement, all variables and given/known data A long, straight wire carries a current of 14 A. Next to the wire is a square loop with sides 1.0m in length. The loop carries a current of 2.5A in the same direction as the wire. Calculate the net force acting on the wire. 2. Relevant equations Magnetic Field for long, straight wire: permeability of free space*I/ 2pi*radius 3. The attempt at a solution I know that the net force is the two forces from the wire and the loop, but I don't understand how to calculate the 2 different magnetic fields.
