Two thin, long parallel wires separated by a distance ‘d’ carry a current of ‘i’ A in the same direction.
Two thin, long parallel wires separated by a distance ‘d’ carry a current of ‘i’ A in the same direction. They will
(1) attract each other with a force of μ0I2/(2πd)
(2) repel each other with a force of μ0I2 / (2πd)
(3) attract each other with a force of μ0I2(2πd2)
(4) repel each other with a force of μ0I2/(2πd2)
