Two wires are placed parallel to each other. What would be the effect of passinga) upward current through both wiresb) an upward current throgh one wire and a downward current through the other.Explain.
a) When the currents through both the wires are in the same direction, the magnetic field due to each midway between them, by right-hand thumb rule, will be in opposite directions. This will result in attraction between the wires. b) When the currents through both the wires are in the opposite directions, the magnetic field due to each midway between them, by right-hand thumb rule, will be in the same direction. This will result in respulsion between the wires.
