In a nut shell the origin of the magnetism is the spin of the electron. Electron spins (rotates like the Earth) around its axes and this spin causes the North and South pole of the magnet. Since electron is indivisible (nobody split it so far) the magnetic poles are also indivisible. Now if you line up many of such electrons they produce stronger magnetic field since this small magnetic fields line up. And this is the big magnet. Now, to answer your question, if you cut big magnet in halves, the small electronic magnetic fields sum up in those halves so that magnet poles are indivisible.

Sure.
Think of a bar magnet as abunch of very small magnets joined in one big bar. In fact, that is what it is. Every small metal particle that make up the magnet is separately magnitized. When they are together, except for the out most poles, N and S cancells each other. When you separate them, the breaking point will have new outer surface. Therefore, each piece gets its own N and S.
When you cut a bar magnet in half, YOU DO get S and N poles in each piece. You can NOT just have a piece that ONLY has S or N on its own.

Magnetic monopoles do not exist in the universe (they havent been discovered but all current theory doesnt allow their existence)
For this reason it is impossable to have a north pole without a corresponding south pole

The half that had the North pole will develop a South pole at the cut end, and the half with the South pole will develop a North.

Yes, you do. Just now, each of them has its own corresponding opposite pole to react to it.
A magnet is really just a magnetic substance that has millions of molecules acting together with each of their own little north and south poles.

Think of a bar magnet as an energy FLOW
(i.e.; direction.)
When you cut it in half the energy is still flowing in the same direction in both of your new magnets.

Yes you do. Each ½ will have it's own N & S poles.
