उत्तर
- They are closed and continuous curves.
- They are directed from the north pole towards the south pole outside the magnet.
- The tangent at any point on a field line gives the direction of the magnetic field at that point.
- Two magnetic lines never intersect each other.
Notes
Students should refer to the answer according to their questions.
