IN a loud speaker there are two magnets. one permanent magnet that always has its northpole pointing in the same direction , and one electro magnet that can change its magnetic field in direction and magnitude. IF both northpoles point into the same direciton ,the speaker cone is pushed out, if both point in opposite directions the speaker cone is pulled in. The direction and magnitude can be controlled by the current passing through the electro magnet.
A loudspeaker uses an electromagnet to convert electrical energy into sound. When an electrical current flows through the coil of wire attached to the speaker cone, it creates a magnetic field that interacts with a permanent magnet in the speaker. This interaction causes the speaker cone to move back and forth, producing sound waves.

Where are the electromagnets in a loudspeaker?
Electromagnets in a loudspeaker are typically located around the voice coil. The voice coil is attached to the speaker cone and moves back and forth in response to the electrical signals. The interaction between the voice coil and the electromagnets produces sound by vibrating the speaker cone.
What material should you use for an electromagnet?
You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.
How does loudspeaker use electromagnet?
A loudspeaker uses an electromagnet to convert electrical signals into sound waves. When an electrical current flows through the coil of wire in the speaker, it creates a magnetic field that interacts with a permanent magnet to move a diaphragm, producing sound waves. The movement of the diaphragm creates changes in air pressure that our ears perceive as sound.
How does a speaker make sound with electric energy?
A speaker uses an electromagnet to convert electric energy into sound waves. When an alternating current flows through the coil of the electromagnet, it causes the coil to move back and forth. This movement is then transferred to the speaker cone, which pushes air molecules, creating sound waves.
What are three ways to make an electromagnetic stronger?
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
What does a loudspeaker use to turn electric energy into sound?
magnets!
