Two parallel long, straight wires are separated by 3.00 cm. One of them carries a current of 2.00 A. The magnetic field at a point halfway between the two wires has magnitude 5.00×10^(−5)T. What is the current in the second wire if its direction is the same as in the first wire?
What is the current in the second wire if its direction is opposite to that in the first wire?
