Question

Identify the INCORRECT statement from among the following

• A. A freely suspended bar magnet points in north-south direction.
• B. Outside a bar magnet, the magnetic field lines are directed from north to south pole.
• C. A number of field lines intersect at a given point inside a magnetic field.
• D. Repulsion is a sure test of magnetism.

Answer 1

Answer:

C. A number of field lines intersect at a given point inside a magnetic field.

• Third statement is incorrect.

• Magnetic field lines never intersect because if they did, it would mean the magnetic field has two directions at that point, which is impossible.

• The non-intersection of magnetic field lines is a direct consequence of the fact that the magnetic field at any point has a unique and well-defined direction.

• This property is crucial for understanding and visualizing magnetic fields.
