Question

A current carrying wire LN is bent in the from shown below. If wire carries a current of 10 A and it is placed in a magnetic field of 5T which acts perpendicular to the paper outwards then it will experience a force

  1. Zero    
  2. 5 N    
  3. 30 N    
  4. 20 N    

The correct answer is: 5 N


    The given wire can be replaced by a straight wire as shown below

    Hence force experienced by the wire
    F equals B i l equals 5 cross times 10 cross times 0.1 equals 5 N
