In speakers, an electromagnet works by receiving an electric current which creates a magnetic field. This magnetic field interacts with the permanent magnet in the speaker, causing it to vibrate. These vibrations produce sound waves that are then amplified and emitted through the speaker cone.

What household appliances have an electromagnet in it?
Some household appliances that have an electromagnet include electric motors, doorbells, speakers, and refrigerators (for the door latch mechanism).
What are some objects that contain an electromagnet?
Some objects that contain an electromagnet include electric motors, speakers, MRI machines, and doorbells. Electromagnets are also used in cranes, magnetic levitation trains, and particle accelerators.
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
Produced by a coil of current-carrying wire wrapped around an iron core?
The electromagnetic field generated by the coil induces magnetism in the iron core, resulting in an electromagnet. This electromagnet can attract or repel other magnetic materials, making it useful in various applications such as in electric motors, relays, and speakers.
Why is soft iron used for the core of an electromagnet?
Soft iron is used for the core of an electromagnet because it can be easily magnetized and demagnetized, allowing the electromagnet to quickly switch its magnetic field on and off. This property makes soft iron ideal for applications where a temporary magnetic field is needed, such as in electromagnets used in electric motors, relays, and speakers.
How does lectromagnet work in loud speakers?
The electromagnet is a very important part of loud speakers. The electromagnet is always placed in the front of the magnet. When the electricity goes through the electromagnet the field is changed and this produces the vibrations in speakers.
How do speakers and headphones work?
Speakers use pulses of electricity to activate a small electromagnet that surrounds another magnet. it has a plastic covering, so as to mimic the vibration of our vocal chords and make noise.
A stereo speakers uses an electromagnet to move the cone?
True .
What household appliances have an electromagnet in it?
Some household appliances that have an electromagnet include electric motors, doorbells, speakers, and refrigerators (for the door latch mechanism).
How do electromagnet fire alarms work?
the electromagnet makes the door close when a fire alarm goes off
Do you have to connect a cell to work an electromagnet?
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
How do small speakers work?
the same way big speakers work
What are some objects that contain an electromagnet?
Some objects that contain an electromagnet include electric motors, speakers, MRI machines, and doorbells. Electromagnets are also used in cranes, magnetic levitation trains, and particle accelerators.
What does a battery contribute to an electromagnet to help it work?
A core
How does an electromagnet work in blender?
it connets to the bottom of the machine
Things that use electromagnets in your house?
Blenders, doorbells, speakers, and probably anything that is related to speaker systems or have speakers in them. Any device with a motor, generator, speaker or microphone, or a transformer has an electromagnet installed.
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
