o ok...so this is what i have: there are going to be two forces, one for the parallel wires 3cm apart (attracting), and the one for the parallel wires 8 cm apart (repulsing). the first force is equal to I*L*sin90*B = [2.5 amps]*[sin90]*[10^-7(telsa*m^2)/amp*m]*[2(2.5amps)/.03m]*L. I would do the...

thanks guys, but so to find the net force on the loop, do i need to find both magnetic forces and electric forces and combine them? i can see now how to find the magnetic force, but from the information given, I am not sure there is an electric force?

Homework Statement A rectangular loop of wire lies in the same plane as a straight wire, as shown http://i30.tinypic.com/347fupw.jpg". There is a current of 2.5 Amperes in both wires. Determine the magnitude and direction of the net force on the loop. Homework Equations Not sure. I am...
