Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
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.
yes

Electromagnets are primarily used to produce electricity Any large scale facility with lots of instruments will definitely have electromagnets in it. Generators in the powerhouse uses big electromagnets to produce AC voltage which is then transported for the commercial or residential use.
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
No. compasses use a complex spinner.
Since electromagnets are used in most large electric motors,the answer is almost all industry.
Electromagnets are stronger and weigh far less than permanent magnets.
