the only sound is from the power source
Yes
sound wave cannot produce magnetic field because magnetic field is created due to flow of electric currents sound is a mechanical wave, sound is produced due to vibration in a medium so sound wave cannot create electric current or magnetic field
transfer/movement of electrons
An instrument for producing sound by means of electric currents.
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.
Yes, acoustic electric guitars can produce sound without amplifiers, but amplifiers are needed to make the sound louder and to adjust the tone and effects.
Sound waves are converted into small electric currents through a process called transduction, which involves a microphone. In a microphone, sound waves cause a diaphragm to vibrate, which in turn moves a coil of wire within a magnetic field. This movement induces a small electric current in the coil, which is then amplified and recorded.
Yes, an electric current can produce sound when passing through a material that vibrates in response to the flow of electrons. This vibration creates sound waves that can be heard. Examples include speakers and buzzers.
Gauss's law: Electric charges produce an electric field. Gauss's law for magnetism: There are no magnetic monopoles. Faraday's law: Time-varying magnetic fields produce an electric field. Ampère's law: Steady currents and time-varying electric fields produce a magnetic field.
solar cells generate electric currents directly from the sun light
Electric currents ... especially in coils.
they use electrical and sound energy
