Question

Which of the following statements given below is not true in the context of magnetic lines of force ?

• A. Magnetic lines of forces are closed continuous curves
• B. No two magnetic lines of force can intersect each other
• C. Magnetic lines of force are close to each other at the poles
• D. They start from the north pole and end on the south pole

Answer 1

Answer: (D)

They start from the north pole and end on the south pole



The magnetic lines of force are closed concentric circles and hence, the starting or ending point cannot be specified exactly except the direction. Therefore, the direction of magnetic field lines outside the magnet is from North Pole to South Pole and the direction of magnetic field lines inside the magnet is from south pole to the north pole. Start and end cannot be found.
