Question

1)Why monopoles exist ? Explain
2) Why magnetic poles exist in pairs explain

Answer 1

Dear student,
A magnetic monopole does not exist. Just as the two faces of a current loop cannot be physically separated, magnetic North pole and the South pole can never be separated even on breaking a magnet to its atomic size. A magnetic field is produced by an electric field and not by a monopole.
The magnetic poles always exist in pairs. It is not possible to separate the two poles of a magnet. If a bar magnet is broken in the middle in two parts each part is found to be a magnet.Thus, the two poles of a magnet exist simultaneously.
