It depends on the type of lamp and the strength of the magnet.
An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them.
Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them.
If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about.
LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.

What happens when you break a magnet into smaller pieces?
You get a bunch of smaller magnets and you will still have north pole.
What happens when you break a magnet?
As you break a magnet, the remnant (broken piece) shall still remain a magnet with the same properties and poles. However, there is only so far a magnet can be broken. Visualize a magnet. Now imagine to have a knife that would keep cutting the magnet into half. It will reach a point that cutting the 'magnet' further would yield into a particle with no magnetic charge whatsoever. This is called a magnetic domain. Cutting a magnetic domain further would yield into a charge-less particle as it would be obviously incorrect to state that an atom of a magnetized steel bar would still remain a magnet.
