What happens to a magnet if you cut it in half?

When we cut a magnet in half, we obtain 2 magnets, each with its own set of north and south poles. We can keep on cutting the resultant magnets in halves and each time, we will obtain 2 new magnets, each working independently as a magnet (with its own north and south poles and its own magnetic field and lines). 

One can think of a magnet as a loaf of bread. Each time we cut...

When we cut a magnet in half, we obtain 2 magnets, each with its own set of north and south poles. We can keep on cutting the resultant magnets in halves and each time, we will obtain 2 new magnets, each working independently as a magnet (with its own north and south poles and its own magnetic field and lines). 

One can think of a magnet as a loaf of bread. Each time we cut the bread, we end up with a slice of bread, which is smaller in size, but is still bread. Similarly, magnets can be cut into a large number of smaller magnets, each of which will act like an independent magnet, with its own magnetic field. One can also think of a magnet as made up of a large number of smaller magnets. 

Hope this helps.
