The textbooks say that if you break a bar magnet into two pieces along its length, each part would still be a bar magnet. And if you continued to break each such piece into two smaller pieces, each would still be a bar magnet, and so on.
In a similar manner, you may say that if you break a bar magnet “along its length into two halves” you would get two slimmer magnets. In theory, or in principle.
However, in reality, if you “cut” a bar magnet into two halves, it is anybody's guess as to whether the pieces would retain the magnetism, because (a) the cutting process would generate a lot of heat, and (b) it would also give rise to a great deal of strong vibrations in the body of the magnet.
Well you can't always trust your textbooks.
Hopefully it helps.
