A rigid square loop of side 'a' and carrying current `I_(2)` is lying on a horizontal surface near a long current `I_(1)` carrying wire in the same plane as shown in figure. The net force on the loop to the wire will be :

Text Solution

Verified by Experts

`F_(res) =(mu_0I_1I_2)/(2pia)a(-hati)+(mu_0I_1I_2)/(2pi(2a))a(hati)=(mu_0I_1I_2)/(4pi)(-hati)`
