By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Noop. Even if you had a bullet that was attracted to a magnet (like an iron bullet), it would have too much kinetic energy to be effected. I guess if you had a really big and thick magnet, it could stop a bullet, just like a book can sometimes stop a bullet. This has nothing to do with magnetism, but just the interaction of mass.
Yes it can because water will not interfere with the magnet as it is working
It is only magnetized when electricity is run through it. Once you stop the electron flow it reverts back to its original state.
No because the magnetic field induced attracts the falling magnet, creating a force which slows down the magnet. If the magnetic field increased to a certain point where the force acting on the magnet was enough to stop the magnet from falling, gravity would act on the bob, causing the magnet to speed up again until it reaches a happy medium speed (or even a terminal speed if you will). When this happens, a changing magnetic field occurs and an induced current is formed again. This cycle repeats.
Yes
You can't. You might be able to demagnetize it, but then it's no longer a magnet, it's just a piece of metal.
magnetic compass will stop working.
a power poiint
i dno

Place a small flat magnet over the hole mimes been working for 3 years now
yes
deoxyiation
no

You can't yet, but rumor has it, the developers Rovio are working on a version for the Torch. Possibly even older BBs with the track pad / pearl.
