Question

Choose the correct statement about the properties of magnetic lines of forces.

• A. Lines of force are not imaginary lines
• B. Lines of force cannot be mapped on paper
• C. Lines of force do not intersect each other
• D. Lines of force always intersect each other

Answer 1

Answer: (C)

Lines of force do not intersect each other

The following are properties of magnetic lines of force:

1. Magnetic lines of force start from the North Pole and end at the South Pole out side the bar magnet.
2. They are continuous through the body of magnet.
3. Magnetic lines of force are closed circular loops.

4. Two magnetic lines of force can not intersect each other because, if they intersect there will be two directions of magnetic field at the point of intersection, which is impossible.

5. Crowded magnetic lines of force show greater magnetic strength and vice-versa.
