3. Parallel wires carrying currents will exert forces on each other. 2098 Each wire produces a magnetic field, which influences the other wire. When the currents in both wires flow in the same direction, then the force is attractive. When the currents flow in opposite directions, then the force is repulsive.

Two wires parallel to each other and seperated by a distance d carry different currents; they exert a force with magnitude F on each other. (a) The wires carry current in the same direction. If the current carried by one of the wires is quintupled and the distance between the wires is divided by three, then what will the force's magnitude be (as a multiple of F) and will it be repulsive or attractive? F ---Select--- attractive repulsive (b) The wires...
