Why magnetic field lines never intersect each other????

If magnetic field lines intersect each other, then at the intersection point there will be two directions of the same field which is not possible. Hence the field lines do not cross or intersect each other.

Answer:

Magnetic lines of force are defined as the curved lines which are used for representing the magnetic field. These lines do not exist but are imaginary lines through the pattern of the magnetic field is explained. These imaginary lines are assumed to originate from the north pole and reach to the south pole by travelling inside the magnet thereby completing the loop.

Properties of magnetic lines of force

  • Magnetic field lines originate from the north pole and merge at the south pole.
  • As the distance between the poles tends to increase, magnetic line density reduces.
  • Inside the magnet, the position of the field lines is from the South Pole to the North Pole.
  • Magnetic lines do not intersect with one another.
  • The magnetic lines strength is the same throughout, and it is proportional to how near the lines are.

 

Reason – The two magnetic field lines do not intersect each other because if they do it means at the point of intersecting the compass needle is showing two different directions which are not possible.
