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.
What else can I help you with?
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.
Where are the electromagnets in a loudspeaker?
Electromagnets are not used in commercially available loudspeakers due to unlinear sound reproduction, noise induced by the electromagnet current and cost. A permanent magnet with a moving coil in the magnet gap is far superior to an electromagnet considering these three parameters.
How does loudspeaker use electromagnet?
The exceptionally strong and steady magnetic field reacts with the alternating field created by the alternating current produced by the audio current flowing in what is known as the voice coil. The Voice Coil is physically attached to the cone that moves the air so you can hear the pressure wave that simulates the current wave-form.
How does a speaker make sound with electric energy?
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
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!
How do you use a electromagnet?

Is loudspeaker an input device?
No, Loudspeaker is an output device.
What is the duration of The Loudspeaker?

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 a stereo speaker use an electromagnet to produce sound?
An electromagnet drives the stereo speaker to provide the sound.
Where are the electromagnets in a loudspeaker?
