Question

When a bar magnet is broken into two pieces, which of the following are true?

(a) The magnet loses its magnetism

(b) The magnet has only north pole left

(c) The magnet has only south pole left

(d) The magnet turns into two new bar magnets

I had been asked this question at a job interview.

My question is based upon Magnetomotive Force and Magnetic Field Strength topic in section Simple Magnetic Circuits of Basic Electrical Engineering

Answer 1

Right option is (d) The magnet turns into two new bar magnets

Explanation: When a bar magnet is broken into two pieces, it forms two different bar magnets. This happens because the broken pieces of the magnet form a separate north and south pole for itself as monopoles do not exist.
