Question

Two circular coils A and B are facing each other as shown in figure. The current i through A can be altered

  1. there will be repulsion between A and B if i is increased    
  2. there will be attraction between A and B if i is increased    
  3. there will be neither attraction nor repulsion when i is changed    
  4. attraction or repulsion between A and B depends on the direction of current. It does not depend whether the current is increased or decreased.    

The correct answer is: there will be repulsion between A and B if i is increased
