Homework Statement
The top wire is 1.00 mm diameter copper wire and is suspended in air due to the two magnetic forces from the bottom two wires. The current flow through the two bottom wires is 95 A in each. Calculate the required current flow in the suspended wire.
Homework Equations
Force between two parallel wires is
F2= u0I1I2l2/(2*pi*d)
The Attempt at a Solution
Fm = Fnp
Fm = u0*95 A * 95 A * l2/(2*pi* .038 m)
But they do give me length...
