You now have 2 bar magnets, each with half the magnetic force of the original.
Each half develops north and south poles.
Each half would have a north pole and a south pole.
The polarity of a magnet does not change if the magnet is cut into pieces. Each piece has the same polarity that it had before. In particular, if you break a bar magnet in half at the midline between the two poles, you will end up with two magnets N-S and N-S. No reversal of polarity occurs.
a norh pole and a south pole
it becomes a magnet in it s own right with north and south poles
The poles are situated at the ends of the bar magnet. The magnetic lines of force run through the magnet, emerge from one end, fold back around the length of the bar of the magnet, and curl back into the other end. The ends are the magnetic poles, and the magnetic lines of force emerge from one and re-enter the magnet at the other. You can see these lines by laying flat a piece of smooth paper over the magnet and sprinkling iron filings over the paper. Because they are light they will be easily moved into alignment by the magnetic field and will visually show the fields arrangement. (Using a piece of paper makes it easy to tidy up. Without it, the filings will stick to the magnet and be difficult to remove.)
The bar magnet becomes two smaller barn magnets.

No, being a magnet, it has a north pole and a south pole. The two can't be separated in a magnet. If you cut the magnet in half, each half will still have a north pole and a half pole.No, being a magnet, it has a north pole and a south pole. The two can't be separated in a magnet.

small magnets lined up north to south
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
opposite poles
You may think that it will be twoseparatenorth and south poles, but the magnetic field is changing the ways, so when you do cut it in half, it will become twoseparatemagnets, each with twonorthand south poles.
If a candy bar was cut in half the mass would decrease.

No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
It is going to need to be divide by the original density and then after you find that out you get your answer.
