Question

Can magnetic field lines intersect each other? Give reason to your answer.

Answer 1

Hint: The space around the poles of a magnet is called the magnetic field, and is represented by magnetic lines of force. The force exerted on one magnet by another one, either of attraction or of repulsion is called the magnetic field. According to Coulomb's first law, unlike poles attract each other and like poles repel each other.

Complete step-by-step solution:
A magnetic material exhibits a magnetic field around itself. This field can be visualized in front of lines originating from the north pole of the magnet and ending at the South Pole .These hypothetical lines are called magnetic field lines.

Properties of magnetic lines of force are:
Magnetic line density reduces as the distance between the poles increases
Magnetic field lines start from the North Pole and end at the South Pole.
Magnetic lines will not intersect with one another.
Two magnetic lines of force cannot intersect each other because if two magnetic field lines intersect there will be two directions of magnetic field at that point which is impossible.
Magnetic forces give information about charge carriers in material by using Hall Effect
Rotating magnetic fields are used in generators.

Note: Students magnetic lines of force which originate from a north pole and end at south pole and there cannot exist an isolated north pole or south pole. Magnetic monopoles do not exist in nature. Earth which produces its own magnetic field. Tesla is a unit of magnetic field strength or magnetic flux density.
