Q. Which of the following statements is incorrect regarding magnetic field lines?

(a) The direction of magnetic field at a point is taken to be the direction in which the north pole a magnetic compass needle points.
(b) Magnetic field lines are closed curves.
(c) If magnetic field lines are parallel and equidistant, they represent zero field strength.
(d) Relative strength of magnetic field is shown by the degree of closeness of the field lines.

The stronger the field around the magnet, the closer are the field lines.

Concept Used: Magnetic field lines

Step 1

The strength of the magnetic field is proportional to the closeness of the magnetic field lines. So, the lines are closer means the magnetic field is stronger.

Step 2

The statement is correct.
