Two long straight wires are oriented parallel to each other with a small separation. The two wires experience a repulsive force between them. You examine one of the wires and find it has an electric current running through it. What must be true of the other wire? O It has zero electric current O It has a net positive charge O It has an electric current in the same direction as the first wire O It has an electric current in the opposite direction to the first wire

A long solenoid that has 870 turns uniformly distributed over a length of 0.420 m produces a magnetic field of magnitude 1.00 x 10-4 T at its center. What current is required in the windings for that to occur? mA Need Help? Read It Master It
