Which of these statements about the properties of a simple bar magnet are correct?

1. North or south poles can exist separately.
2. Magnetism is concentrated at the extremities of the bar.

  • A
    Both 1 and 2 are incorrect.
  • B
    1 is correct, 2 is incorrect.
  • C
    1 is incorrect, 2 is correct.
  • D
    Both 1 and 2 are correct.
  • North or south poles can exist separately – This statement is incorrect as any magnet has two different poles – North and South. The magnetic lines around a magnetic material always go from the North to the South pole. If these lines were nonexistent, the material would have no magnetic properties. There is no such magnet that has only a South pole.
  • Magnetism is concentrated at the extremities of the bar – This statement is correct. The magnetic field lines are the strongest at the poles.
