An infinitely long straight wire carries a conventional current I as shown in the The rectangular loop carries a conventional current I in the clockwise direction Find the net force on the rectangular loop

Text Solution

Verified by Experts

The correct Answer is:
`(mu_(0)II'C)/(2pi) [(1)/(a) -(1)/(b)] "t o the left"`
Force on `AB` and `CD` will be equal and opposite and opposite
`F_("net") = [F_(AD) -F_(CB)] "left" `
`= (mu_(0))/(4pi) (2IIC)/(a) - (mu_(0))/(4pi) (2II'C)/(b)`
`=(mu_(0))/(2pi) II,C [(1)/(a) -(1)/(b)]`
