Question

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 a steady current I is established in the wire as shown in figure, the loop will.

  1. rotate about an axis parallel to the wire    
  2. move away from the wire    
  3. move towards    
  4. remain stationary    

The correct answer is: move towards
