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.
Electric motors, televisions, maglev trains, telephones, computers and many other modern devices use electromagnets

Louis Roberts invented a gaseous discharge device. Mr. Roberts holds eleven patents for electronic devices and is the author of papers on electromagnetism, optics, and microwaves.
Electromechanics combines the sciences of electromagnetism of electrical engineering and mechanics.Electromechanical devices are those that combine electrical and mechanical parts. These include electric motors, loudspeakers, some fire alarms and mechanical devices powered by them, such as calculators and adding machines; switches, solenoids, relays, crossbar switches and stepping switches.
the basic system uses electromagnetism
Any type of device that would need to be converted from AC to DC power would use a voltage converter. Devices such as televisions, monitors, and other electronic devices could use a voltage converter.

Electromagnets in scrapyards are used to carry metal around. Electromagnets are better than normal magnets because you can turn the current on and off.

There is no relation between medical uses of electromagnetic energy and alternative devices. There are no available scientific evidence to support claims in treating any diseases with the use of electromagnetism.

Electromagnetism is one of the four fundamental forces, the other three being the Strong Atomic Force, the Weak Atomic Force, and Gravity. Electromagnetism is used for nearly everything we do involving power, motors, nerves, and chemistry, just to name a few.
if a component has an electrical connection and movement is created by or within the component, then that component will use an electromagnet. Devices such as relays, solenoids and motors, use electromagnets to create movement. Ignition coils and transformers use electromagnetic induction to raise or lower voltage outputs
They both use electromagnetism.
