A rectangular loop carrying a current ` i` is situated near a long straight wire such that the wire is parallel to one of the sides of the loop and is in the plane of the loop . If steady current ` I` is established in the wire as shown in the figure ,

Options

A. Rotate about an axis parallel to the wire
B. Move away from the wire or towards right
C. Move towards the wire
D. Remain stationary

Answer

C

Explanation

Since , `F_(1) gt F_(2)`
As `r_(1) lt r_(2) , [F = (mu_(0) I_(1) I_(2))/(2pi r)]`
The loop will move towards the wire.
