Speakers - Electromagnets in Daily Life
http://electromagnets.weebly.com/speakers.html
The voice coil is the electromagnetic part of the speaker. The voice coil is a tight coil of wire hooked up the the speaker's power source. Alternating current electricity is run through the voice coil, causing it to constantly switch polarity. The magnet is a …
Speaker Magnets: Why Do Speakers Have Magnets? | Nucoustics
https://nucoustics.com/speakers/why-do-speakers-have-magnets/
There are speakers in magnets because when an electric current is passed through the wire on either side of it, it creates a magnetic field - letting the voice coil move freely back and forth, which creates sound waves that you then hear with your ears. This is because a speaker is a type of device called a transducer.

When the coil moves, it pushes and pulls on the speaker cone. This vibrates the air in front of the speaker, creating sound waves. The electrical audio signal can also be interpreted as a wave. The frequency and amplitude of this wave, which represents the original sound wave, dictates the rate and distance that the voice coil moves.

A speaker converts electrical energy to mechanical/acoustical energy. It uses a coil of wire, which acts as an electromagnet, set inside of a magnetic gap of a permanent magnet. The following demo shows the main components of a woofer. Holding your cursor over the individual buttons will highlight the respective component.
How do electromagnets in speakers work? - Quora
https://www.quora.com/How-do-electromagnets-in-speakers-work
The electricity for the electromagnet of the speaker comes from the sound amplifier. As a result, the electromagnet produces a time varying magnetic field. The forces of attraction and repulsion of this electromagnet causes the vibration of the diaphragm, which vibrates the air, resulting in the creation of sound. 839 views View upvotes
Why Do Speakers Have Magnets? - CarSoundPro

Normally speakers contain permanent magnets for producing sound using the property of electromagnetism when electric signals are passed through a coil kept in the magnetic field of Permanent Magnet. (ref: How Speakers Work frm How Stuff works). now what i have tried to do here is replaced the permanent magnet of the speaker with an electromagnet.
