Why don't we use permanent magnets in electric bell?
permanent magnets are not used in electric bells because they do not make the bells to ring well
What is true of permanent magnets?
Permanent magnets contain a current-carrying wire.
Witch part of an electic motor repels the poles of the permanent magnets?
The part of an electric motor that repels the poles of the permanent magnets is the fly wheel.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What magnets are used for?
Some magnets are used to make electric motors and generators.Some magnets are used for car doors,door hinges,computers,hovers,blenders, CD players,washing machines, fax machines, escalators, elevalators,loud speakers,credit cards,tv,fridge doors,toys,jewelry, and elecric toothbrushes, magnets are used in junk yards to make new cars too,magnets are used in roller coasters.These are called electro magnets and you can turn them on and off.and they are also used in the new unistation 360 witch is awesome.

What metal is used in low melting alloys and 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.
Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+
How are temporary and permanent magnets alike?
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.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
What is true of permanent magnets?
Permanent magnets contain a current-carrying wire.
Are permanent magnets only attracted to other permanent magnets?
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
What devices use 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.
What is used instead of field coils in an electric motor?
