They age through magnetic tension with nitrogen, sulphur monoxide and many other gases
Nothing, elctro magnets act just the same as permanent magnets
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
Permanent magnets are used in food processing to remove metal fragments resulting from the manufacturing process. Magnets are also used in recycling centers to separate iron. A magnetic resonance imaging machine uses a magnet.

permanent magnets
Permanent magnets contain a current-carrying wire.
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
No, electromagnets are not permanent.
Permanent magnets aren't bad. period. I do not know where you heard that but whatevs..
Permanent magnets can be purchased from sites such as Magnet Sales and PML India. A permanent magnet is more resistant to factors that would demagnetise it than regular magnets.
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
permanent magnets
A permanent magnet can affect magnets and electromagnets.
They can be demagnetized. Because nothing can be permanent :-)
Yes Permanent magnets is the term used to describe magnets that are always magnetic, an non permanent magnet would be an electro magnet which is only a magnet when an electric current is put through it.
