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.
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Place a small flat magnet over the hole mimes been working for 3 years now
yes
no
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.
the other 1 does stop working NO it does not
Yes it will stop heating up...........
Quit, retire.Retire means to stop working.
Yes it can because water will not interfere with the magnet as it is working
It is possible for aÊrelay toÊstop working. A relay can overheat or stop working due to a shortage in the wiring.
It is only magnetized when electricity is run through it. Once you stop the electron flow it reverts back to its original state.
