Question

Choose the incorrect statement from the following regarding magnetic lines of force:

• A. The direction of magnetic field at a point is taken to be the direction in which the north pole of a magnetic compass needle points when placed at that point.
• 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.

Answer 1

The correct option is C

If magnetic field lines are parallel and equidistant, they represent zero field strength.

If magnetic field lines are parallel and equidistant, they represent non-zero uniform field strength.
