Magnetic lines of force due to a bar magnet do not intersect because
Correct answer: A. A point always has a single net magnetic field
- A. A point always has a single net magnetic field
- B. The lines never cross each other
- C. The lines need magnetic lenses to be made to intersect
- D. None of the above
Explanation
The correct answer is that a point always has a single net magnetic field. Magnetic field lines are conceptual tools used to depict the direction and strength of a magnetic field. At any particular point in a magnetic field, there is a unique direction of the magnetic field, which is why the lines do not intersect. If they did, it would imply that at the intersection point, there are two different directions of the magnetic field, which is not possible. Option B repeats the question without providing a reason. Option C introduces a concept not related to the properties of magnetic field lines. Option D dismisses the possibility of a correct answer among the given choices.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
