Question

Which of the following statements is correct?

Options

• Magnetic field lines do not form closed loops.

• Magnetic field lines start from north pole and end at south pole of a magnet.

• The tangent at a point on a magnetic field line represents the direction of the magnetic field at that point.

• Two magnetic field lines may intersect each other.

Answer 1

The tangent at a point on a magnetic field line represents the direction of the magnetic field at that point.

Explanation:

Magnetic field lines do form closed loops; magnetic field lines do exist also from south pole to north pole inside the magnet, and two magnetic field lines never intersect each other.
