If so, then that electromagnet converts voice frequency electrical pulses to sound by moving the diaphragm in the speaker.
yes
hmmm
Yes
radios, telephones, and coumputers
phones and electric motors definitely do!
nobody no and this is the internet
no there is no use of electromagnets in iron box
Electromagnets are widely used in the society. An advantage is that humans use electromagnets in all kinds of useful utensils like doorbells, telephones, cranes, computer disks, mobile phones, televisions and so on. Also eye surgeons, while performing operations, use electromagnetic devices to recover the patient.
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
no
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.
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.
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.
yes
