magnets
Nothing, elctro magnets act just the same as permanent magnets
Nickel
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.
The materials attracted by magnets are called magenetic materials.
Permanent magnets.
Iron, nickel, and cobalt are used to create permanent magnets.
Permanent magnets.
they're both magnets . they can both stick to iron-made materials. They are different because temporary magnets only last a little and permanent magnets last a long time.
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.
Magentic materials are mainly of three types. 1) Diamagnetic materials 2) Paramagnetic materials 3) Ferromagnetic materials Diamagnetic meterials are those that do not have megnetic property. Para magnets can be used as temporary magnets Ferro magnetic materials are tose which are permanent magnets. The magnets made from magnets that easily lose their magnetis catue are paramagnets.
Yes - in magentic terms, "hardness" = "permanence".
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
Aluminum, Brass, Lead, Plastic or Paper because those materials are non-magnetic!
No, electromagnets are not permanent.
