the current flows to the voice coil, and at first the polarity of the current is the same as that of the speaker magnet, causing the voice coil to be pushed away from the magnet pushing the cone outward. then as the current cycles through it becomes opposite from the magnet cauing the voicecoil and cone to be pulled back in

How could you show that a loudspeaker has magnet in it?
To demonstrate that a loudspeaker has a magnet, you can use a small ferromagnetic object, like a paperclip. Bring the paperclip close to the speaker; if it is attracted, this indicates the presence of a magnetic field, confirming that a magnet is inside. Additionally, you can disassemble the speaker (if possible) and visually inspect the components, where the magnet is typically found near the voice coil. Finally, measuring the speaker's impedance with a multimeter can also suggest the presence of a magnet, as it affects the electrical properties of the speaker.
How magnets are used in speakers?
Coils of copper wire are wrapped around the magnets. The music in your radio is converted to electrical pulses that move thru those copper wires wrapped around those magnets. The direction and strength of those electrical pulses causes them to have a magnetic reaction with the flowing electricity. This magnetic reaction is connected to a moving mechanism that is attached to your speaker cone. The way the cone moves back and forth from this coil reacting to the magnet recreates the sound coming from the radio station So the magnet is just to turn your speaker into a big electromagnet that moves like a solenoid in response to changing electrical impulses that duplicate the sound generated. The magnet has a constant field, but the coil of wire is the electromagnet but it reacts to permanent magnet. Usually the bigger the permanent magnet the bigger the sound the speaker can produce because it can generate stronger pulses from that solenoid coil that reacts to the magnet under electrical impulses
What kind of magnets are in speakers?
There is usually a large circular magnet in speakers. When an electricial current is put through the speaker cone at a certain frequency it makes the magnetic fields around the magnet change. The cone is connected to the diaphragm of the speaker which vibrates, pushing the air, creating sound waves.
What is the loudspeaker used to produce high frequency sound called?
The loudspeaker used to produce high frequency sound is called a tweeter. Tweeters are designed to reproduce frequencies in the higher range of the audio spectrum, typically above 2,000 Hz. They are commonly used in audio systems to enhance the clarity and detail of sound reproduction.
Why bar magnet is not used in speakers?
Bar magnets are not typically used in speakers because they are relatively large and heavy compared to other types of magnets, making them less practical for the size constraints of speaker designs. Additionally, bar magnets can lose their magnetism over time due to demagnetization, which could affect the performance of the speaker. Instead, smaller and more powerful magnets, such as neodymium magnets, are commonly used in speakers.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
What is another name for a speaker?
Another name for a speaker is a loudspeaker.
How does a loudspeaker use a electromagnet?
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.
Why is a magnet used in a speaker?
A magnet is used in a speaker to create a magnetic field that interacts with an electrical current, causing the speaker cone to vibrate and produce sound waves.
How do electromagnets in a loudspeaker work?
Electromagnets in a loudspeaker work by converting electrical signals into sound waves. When an electrical current flows through the coil of wire in the magnet, it creates a magnetic field that interacts with a permanent magnet to move the speaker cone back and forth. This movement generates vibrations in the air, which we perceive as sound.
How a loudspeaker works?
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
How do you show that a loudspeaker has a magnet inside it?
Ask aba6iii :)!
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.
What are the uses of loudspeaker?
we used speaker in marrige and party..............., many time speaker use as enjoy for your birthday. all people use it because it is the best things of enjoy.....
How to remove magnet from a speaker?
To remove a magnet in a speaker, first detach the grill in the front of the speaker, second unscrew the speaker after that remove the speaker from the cabinet and cut the speaker cone. Lastly, gently discard the magnet from the speaker cone.
Does iPhone have loudspeaker?
All models of the iPhone come with a speaker.
In Which device is magnetic field present?
1 example is an audio loudspeaker device because a coil and magnet is used to create the sound effect.
