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.

What did black inventor Louis Roberts invent?
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.
What is electro-mechanics means?
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.
Meaning of propulsion system in maglev?
the basic system uses electromagnetism
What type of devices would a voltage converter be used for?
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.
Which WC flushing devices is not permitted for use in a house?
a flushing valve
What are some devices that use electromagnetism?
Electromagnets in scrapyards are used to carry metal around. Electromagnets are better than normal magnets because you can turn the current on and off.
What kind of energy does an electromagnet use?
electromagnetism
What has the author Herbert H Woodson written?
Herbert H. Woodson has written: 'Electromechanical dynamics' -- subject(s): Dynamics, Electromagnetic devices, Electromagnetism, Electromechanical devices
What is the relation between medical and electromagnetic?
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.
What has the author Nathan Ida written?
Nathan Ida has written: 'Electromagnetics and calculation of fields' -- subject(s): Electromagnetism, Electromagnetic fields 'Engineering electromagnetics' -- subject(s): Mathematics, Electromagnetism, Electromagnetic devices, Mathematical models
What is electromagnetism used for?
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.
How electromagnetism generates rotary movement?
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
How do electric and magnetic field interact in an electromagnetic wave?
They both use electromagnetism.
What has your understanding of electromagnetism led to?
what has our understanding of electromagnetism led to?
What has the author Paul Lorrain written?
Paul Lorrain has written: 'Solutions manual for electromagnetism' 'Electromagnetism' -- subject(s): Electromagnetism 'Fundamentals of electromagnetic phenomena' -- subject(s): Electromagnetism
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
What do you use electromagnetism in?
Speakers, cranes, roller, coasters, door bells, and many more things
