What are the advantages and disadvantages do electromagnets have?
There are many reasons why electromagnets shouldn't be used. For example, permanent magnets are better to use economically because there is no cost of operation, like an electromagnet. There is also no maintenance or hardly any setup required. For permanent magnets, they can be used for a lot longer than electromagnets becausecan be used in hazardous places and are they are unaffected by shock or vibrations. Electromagnets require electricity to run, which costs money. They also burnout or lose its magnetism after a while. There are also many reasons why electromagnets should be used. For an electromagnet, a person could easily control the power of the magnetism, unlike the permanent magnet which has the same intensity throughout. A person could also turn the power of the magnet on and off, which can become useful in certain situations. An electromagnet can also be made stronger than permanent magnets. The electromagnet also has a good field of depth, unlike the permanent magnets limited field depth.
What have electromagnets?
Quite a lot of things, speakers, telephones, tatoo guns, certain componets in computers, (fans) industrinal -to pick up cars, scrap, ect, mri machines, and a hole host of other things.

How are electromagnet usful?
Electromagnets are used in many ways. Televisions use electromagnets to direct the electron beam, whereas loudspeakers and earphones use electromagnets to push the diaphragm forwards.
Why are electromagnets used in the process of corn oil production?
Electromagnets aren't "directly" used in corn oil production. Electromagnets find a lot of industrial applications, but usually only to lift things or hold them in place. This means that they won't be lifting or holding stuff that isn't ferromagnetic. There may be electromagnets in use within, say, and ADM or Cargill corn oil plant, but it isn't like they are critical. Now if we were lifting scrap iron from a pile in a wrecking yard into a gondola car, the electromagnet is the way to go.
What is the source of electromagnet?
An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).
How many telephones are there in Canada?
a lot of phones
