the best explanation I have found

I'll be using this video with my middle school science students. Good explanation!

What an excellent explanation!.

THANKS FOR SHARING YOUR EXCELLENT VIDEO

Very helpful. Appreciate it

short,brief and clear thank you

Nice explanation thank you so much

Amazing explanation

Really helpful....!!!!

THANK YOU SO MUCH!!!

i like the way he moved the coil up and down ;)

Hello Paul. Very nice, clear instructive video, which I may watch one or two more times to really integrate the information. I am just beginning to learn this kind of thing. I wonder if you might help me with a project I am trying to do? Can you please tell me how to daisy-chain several speakers? Just the naked speaker like you show in the video, not the ones in speaker boxes. I would like to daisy-chain 3 or more 8 Ohm .25 W 57 mm Round speakers, all with North face polarity. The first one would be attached to an output device via its + pole. The device will be a 1 kHz DC supply one. Would this kind of array even work without shorting out or otherwise failing? If yes, should they be set a certain distance apart in order to not interfere with each other? Thanks in advance!

Thanks sir

Although I know the biz on speakers, your great vid will make it easier to explain to my grandies when I build them a demo speaker. Then I will get them to build one. My dad was a radtech...some of it rubbed off..lol.

Thanks sir .....

How far do the magnets emit a wave or magnetic attraction or detraction from the magnet itself into the outside of the speaker (front and behind). In other words, how far would magnets travel in strength outside the speaker? Does the strength normally dramatically reduce in a short distance? Say like 3 feet? Would it be possible to measure a strong magnetic wave at this distance, or has it lost the significance of its power?

Thanks

On the motor effect, I’m having a hard time understanding the dynamics between electricity, magnetism, and kinetic energy. First, there is the electromagnetic spectrum. I don’t understand if or where electricity or magnetism appear on the spectrum. Is electromagnetic spectrum different than an electrical spectrum, if there is such a thing? Or is there a magnetic spectrum? I’m not sure what these are. And I’ve heard sound waves, compression waves, are on the electromagnetic spectrum. How can all these things be on the same spectrum and interact with each other to reproduce sound in a speaker or microphone?

The highest pressure is had when the driver is all the way in, not out, assuming steady state and the acoustic environment being mass like such as free space.

What is the significance of the North magnet.ike how does it affect the movement

I just wanted to know about the exact possession of the coil with regards to the magnet?

is it increase the coil..can increase the sound??

Thank you

It is better than any other one.

Could you please explain why you use the right hand rule? Many thanks in advance. Great Video.

I have a video that covers the hand rules that hopefully should answer your question.

dear sir, which softwares and video camera are used to create this video ?

I use a Canon dslr for live video. For screen demos I use Promethean Inspire and Quicktime for the screen capture. I use Adobe Premiere for the editing.

Thank you for the video. Why is the magnetic pole 'north' on the inside of the magnet?Are all magnets with a hole in the center this way by nature? What about the other surfaces of the magnet, do they all have a pole?

he explained it wrong the top of the magnet is north and bottom is south and the south is carryed to the center of the cone by the steel plate on the bottom and north is carryed up and closer to the coil by the top plate.

The idea of expressing as monopole wasn't my intention ( I know they dont exist) but that is how it sounds, so my eror. I have an explanation and correction it in the description

Nice explain... But how is it produced different types of sound like music?????

@PhysicsHigh

6 жыл бұрын

Music is simply multiple frequencies creating complex waveforms. Since the input is AC but complex like the waveforms the speaker receives, the speaker vibrates with that complex frequency pattern

Ok very good

Speakers are so simple! Companies who sell them to us have been ripping us off for years...

the physics is simple. the difference between a good and bad quality speaker is huge though

Could you do AC induction motors and Universal motors as one of your next topics?

good suggestion - I am back at work next week so I can work on a video using some of the motors we have in the storeroom

the title lmao

There's something funny about the way the magnet is shown (e.g. at 3'00, 3'40") : it seems to consist of separate north and south poles! All magnets have to have both...I'm now searching for other sources that explain the magnet design more clearly.

You are correct. There is only one magnet in most speakers. The north connected to the front plate. The south or the base of the magnet is connected to the back-plate and pole-piece. The pole-piece is in the centre.

But in my book its opposite. The North is in the middle and South in its both sides.Is it correct 🤔🤔

so if u use dc current the speaker wouldn't work?

@PhysicsHigh

Correct if the current is unchanging. In a rectified DC supply you will get some vibration

There is a mistake in the video! There is only one magnet!! the top is the Front plate or Front pole. It is a metal plate, not a magnet!! Please correct!

close but a little off you explained it wrong the top of the magnet is north and bottom is south (single pole magnets are rare)and the south is carryed to the center of the coil by the steel plate on the bottom and north is carryed up and closer to the coil by the top plate. nice video though and thanks for sharing

Whats different with mike almost same, but its work different

Microphone works due to induction. In this case sound vibration causes wires to move in magnetic field inducing an EMF
