Question

Write any two properties of magnetic field lines.

Hint:

Magnetic field lines represent the direction and strength of the magnetic field, always forming closed loops.

Answer 1

1. Magnetic field lines never intersect.
Each magnetic field line represents a unique direction of the field at that point, so they cannot cross each other.
2. Magnetic field lines emerge from the north pole and terminate at the south pole.
Outside a magnet, field lines travel from the north pole to the south pole, while inside the magnet, they move from the south pole to the north pole, forming closed loops.
