no it is not .
a temporary magnet is used instead.
If you use a permanent magnet, the doorbell will keep on ringing
Iron, nickel, and cobalt are used to create permanent magnets.
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.
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
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 not used in electric bells because they do not make the bells to ring well
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.
False permanent magnets can but electromagnets need a running current A+

Permanent magnets contain a current-carrying wire.

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.
