The microphone works by producing a small induced voltage in a coil from the effect of sound waves hitting a diaphragm. It is very similar to a loudspeaker in reverse with a diaphragm instead of a paper cone. This type of microphone is called a moving coil microphone. The sound waves strike the diaphragm and move it backwards and forwards at the same frequency as the sound (like the way the ear drum is moved inside the ear). The moving diaphragm moves the coil backwards and forwards which induces a changing current at the same frequency as the sound. This changing current (called the signal) is sent to an amplifier which makes the changing current big enough to be used for recording or to drive loudspeakers. The loudspeaker reconverts the changing current back into the original sound. A microphone converts the sound energy into electrical energy.

What brand of microphones do recording studios use?
Studios use a variety of microphones, and choose between them depending on the situation. Condensor microphones are widely used in recording studios, but diaphram and dynamic microphones are often used as well.
Do ipods use electromagnets?
no
Do microphones have magnets?
Some types of microphones, like dynamic microphones, contain magnets. The magnets are typically used in the mechanism that converts sound waves into electrical signals. Other microphones, such as condenser microphones, do not use magnets in their design.
Do fans use electromagnets?
Yes, some fans use electromagnets in their motors to generate the magnetic field needed for rotation. These electromagnets are energized by an electrical current to produce the desired magnetic force.
Did they use microphones in the Greek theatre?
no.
How are electromagnet usful?
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.
What do factories use electromagnets for?
yes
How do you ancient Greeks use electromagnets?
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
