phones and electric motors definitely do!
True...
Yes it did
All electric motors are electromagnets.
Since electromagnets are used in most large electric motors,the answer is almost all industry.
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.
Many electrical and electronic devices use electromagnets, including telephones, sound speakers, maglev trains, junkyard cranes, and doorbells. Electric motors create an electromagnetic field around a permanent magnet, as do the generators used to create electric power.

Magnets are used to make electric motors and generators. Without these electric motors and generators we would not have telephones, lights, electric heat, television, or computers. Some items that use electromagnets are: Maglev trains, car crushers, scrap metal sorters, telephones, computers, doorbells, tape recorders etc. Magnets are also used in compasses to show attraction and repulsion. Magnetized compasses are used to detect underground metal pipes.

Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
Direct electric current cannot be used to operate D. Transformers.
Electromagnetism is used in electric motors, computer hard drives (and other magnetic storage media), junkyard electromagnets, televisions, particle accelerators, MRIs, and many other devices.
