Consider the following statements: If a piece of bar magnet is broken into two equally long pieces, the pieces will not lose the magnetic properties. Magnetic properties of a substance lie in the atomic level. Which of the statements given above is/are correct ? Correct Answer Both 1 and 2

CONCEPT:

  • Bar Magnet: A bar magnet consists of two equal and opposite magnetic pole separated by a small distance. Poles are not exactly at the ends.
  • The shortest distance between two poles is called effective length (Le) and is less than its geometric length (Lg) for bar magnet.

EXPLANATION:

  • If a bar magnet is broken into two long pieces, then each piece will behave as an individual magnet because the new poles are formed at the broken ends thus, broken pieces of magnet never lose their magnetic properties. Therefore statement 1 is correct.
  • As we know that moving charge particle produces a magnetic field, thus magnetism at atomic /sub-atomic levels is mostly due to charged particles called electrons. Therefore statement 2 is correct.
