Six. Every bar magnet has 2 poles. If a bar magnet is broken, each resultant piece will be a bar magnet in its own right.
The shards each have new north and south poles. It is impossible to create a magnet with only one pole.
You have two magnets.
Each half becomes a new bar magnet with two magnetic poles
Nothing
The magnet would still have a north and a south pole. No matter how small the magnet is it will always have a north and south pole.
You now have 2 bar magnets, each with half the magnetic force of the original.
Nothing happens to properties because if it broken it still has north pole and south pole. Even if magnet broke into smallest piece it would still have same property.
Move towards the U magnet so that the poles attach.
Each half would have a north pole and a south pole.
Field strength will be one half as strong.
If a bar magnet is broken in half, each half is a magnet with its own north and south pole. The force used to break the magnet will also tend to partially demagnetize the magnet, although that might be a minor effect.
The magnet would still have a north and a south pole. No matter how small the magnet is it will always have a north and south pole.
The bar magnet becomes two smaller barn magnets.
The north pole and the south pole. Half of the magnet is red and the other half is blue.
2 new magnets
You now have 2 bar magnets, each with half the magnetic force of the original.
A bar magnet has two poles, a north and a south. When you break a bar magnet into to pieces, you create two bar magnets, each with a north and a south pole. So the total number of poles will then be four.

The ends of a bar magnet broken in two will still attract one another. Imagine a bar magnet with a north magnetic pole and a south magnetic pole: N----------------S Now imagine that the magnet is broken in the middle: N-------//--------S The two existing poles cannot change, but neither is it possible to have a North pole without a south, or vice-versa, so the separated parts will now look like this: N-------S N--------S The south pole of the leftmost section sits next to the North pole of that on the right, and they will be attracted to one another.
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
