I need a tiny magnet. I have a round one (a fridge magnet) that is nice and small, and it would be nice to have it in two halves, but I am worried that the process of cutting it might mess up its magnetism.

You can indeed produce two separate permanent magnets by cutting it in half. A few things you must be concerned about though.
1) Do not mechanically hit the magnet too hard.
2) Do not heat it up too much (blow torch cutting out of the question, haha).
3) Do not induce a reverse magnetic flux (unlikely you will do this either, haha).
These three things can impart enough energy to the magnet that its "magnetic domains" will randomize (as opposed to the aligned nature of the domains in a permanent magnet). So, just clamp the magnet in place and use a fine cutting tool of your choice. If you have one of those Dremel tools it might have a fine cutting attachment.
Then again, magnets are cheap. Why not just buy a bag of new ones the size you want?

Uggh...a magnet is very hard to cut in exactly two halves, because they are so fragile. They break very easily. I had too neo-dynamium-boron magnets stuck together, but when I yanked them apart, they chipped and a lot of pieces got stuck on the two magnets. Not to mention that inhaling these little pieces can kill or injure you. So be very careful when you do this. I would use like a kitchen knife or scissors (although the magnets might fly out). As for the magnetism, when you cut them into pieces, the two halves will each automatically gain a north and south pole. No magnet has one pole whether split or not.

once you chop back basically slightly pipe into 2 you get 2 smaller products of pipe additionally. magnificent. and additionally you besides could get 2 halves of the pipe. once you chop back a magnet in 2 you get 2 smaller products of the magnet. and that they are 2 halves of the only magnet. yet because of the fact the magnetic field is basically a capability and a course ( vector quantity ) then each and each one million/2 additionally components a course. and that they each and each furnish one million/2 the magnetic field of the two at the same time. there is not any longer a north variety of magnetism and a south variety of magnetism. those words are purely used to help human beings comprehend and describe some thing that has a course.

Theoritically a magnet can be cut into two pieces giving you two magnets.
But in practice, the process of cutting makes the magnet domains vibrate and the magnet looses its magntism by a large amount.

The magnetism is in the strongly aligned atoms. That aspect of the magnet is through out the material. Cutting it in half just gives you 2 pieces of the same kind of material with the same atomic structural alignment.

Use a pair of scissors.
You'll have to smaller magnets after cutting.
They don't even have to be the same size.

no it will not - you will get two perfectly fine magnets.
