Question

7. Is it possible to separate the poles of a magnet? Give reasons for your answer.

Answer 1

$\huge \boxed{answer}$

No. A magnetic pole can never be isolated.

Let us consider a bar magnet. If we break a bar magnet into two halves, both the parts will independently act as two separate magnets with 2 different set of poles. This happens so because magnetic field lines always form a closed loop and when magnetic field lines originate from one pole it is necessary to have another opposite pole so that magnetic field lines can enter it and form a closed loop.

The electrons in the atoms of magnetic material spin around the nucleus in mainly only one direction. This creates a more negative side and a more positive side in the magnet which makes the north pole and the south pole of the magnet.

Answer 2

Explanation:

There is never an isolated pole (a monopole). All magnets attract iron, such as that in a refrigerator door. However, magnets may attract or repel other magnets. Experimentation shows that all magnets have two poles.
