Question

(i) Mention any two properties of magnetic field lines.

Hint:

Magnetic field lines always form closed loops, and they never intersect. A useful way to remember is that magnetic field lines "flow" in a circular fashion around the magnet or conductor.

Answer 1

Magnetic field lines have the following properties: 1. Magnetic field lines are closed curves:
Magnetic field lines do not have a starting or ending point. They form closed loops, emerging from the north pole of a magnet and merging at the south pole. Inside the magnet, they run from the south pole to the north pole.
2. Magnetic field lines are continuous and never intersect:
The magnetic field lines are continuous, and they never intersect each other. If two lines were to intersect, it would imply that the magnetic field has two directions at that point, which is not possible.
