A rigid square loop of side ‘a’ and carrying current I2 is lying on a horizontal surface near a long current I1 carrying wire in the same plane as shown in figure. The net force on the loop due to the wire will be –
(1) zero
(2) Repulsive and equal to μ0I1I2/4π
(3) Repulsive and equal to μ0I1I2/2π
(4) Attractive and equal to μ0I1I2/3π
