When two long parallel wires, hanging freely, are connected in series to a battery, Why do they come closer to each other? Reason (r): Wires carrying current in opposite directions repel each other.
1) The wires are attracted to each other due to the magnetic field created by the current.
2) The wires are repelled by the magnetic field created by the current.
3) The wires are attracted to each other due to the electric field created by the current.
4) The wires are repelled by the electric field created by the current
