If a magnet loses its magnetism due to being hit like a tack hammer that is magnetic can it be remagnetized?
You can usually remagnetize a depolarized magnet by laying it down next to another magnet for several hours or days depending on how strong the second magnet is. You can also place the bar inside a coil of wire (shaped like a spring) that has a dc current running thru the coil. As before, this process may take hours or days depending on how large the current is. You can speed things up a bit by warming the bar before placing it next to the magnet or placing it in the coil.

How does a magnet work in a speaker?
From what i have been learnt, the magnet is connected to the diaphragm (the material which covers it) of the speaker and as electric current is passed in this causes the magnet to 'Push' and 'Pull' on the diaphragm making this move resulting in sound waves being produced, these sound waves then enter your ear making you hear the noise. So the magnet helps produce the sound you hear from a speaker.
