Does the size of a magnet affect its range?

[berkeman]

This is the sipmle version of my system for a short dectance

How do you plan to clock this communication system? Is it based on precise clocks at each end (like RS-232), or will you embed a clock in your communication channel like in Differential Manchester Coded communications?

Google each of those if you don't understand my question, and after you have done that reading, feel free to post your questions about that reading here if you don't understand the concept of clocking in communication.

I do understand every signal will close elctrical syrcal by the movment of the the magnet and i going to use the simple binary packet protocol of compiters

PF AI Translation gives:

"I do understand that every signal will close electrical Southern California by the movement of the magnet, and I am going to use the simple binary packet protocol of computers."

I don't understand the Southern California reference, but whatever. Computers use synchronous signalling where a clock accompanies the data. So you will have to say how you plan to send the clock signal with your magnets in addition to the data signal. Will you use two Tx magnets and two Rx magnets to send the data and clock?

 

[danielhaish]

It going to have time counter between two signal if the time between the signal is small so it 0 if is biger then it 1 like morc code

 

[berkeman]

like morc code

So the code will rely on a recovered clock, based on the width of the symbol. That's fine. It's not how you transmit the fastest data, but Morse code is not aimed at fast data transmission. It is aimed at reliable data transmission at human speeds.

Anyway, I think your main question is about using flipping magnetic fields to transmit data. You can do that, but it is far from the best way to do it. Have you tried building this experiment yet?

 

[danielhaish]

No i just was wondering if it possible

It is possible for short distances, but there are much better ways to communicate data wirelessly over longer distances. Can you guess at a few of those better ways?

 

[danielhaish]

Yap Voice waves like radio ,radiation,light, i think that i know how to use this idea for longer distance but i don't really want to tell

Ok thanx

I am typing on a phone is it worng?

Even if you type on a phone, there is no reason not to check what you have typed. If you want the best from PF then you need to make a bit more effort, I think.

I meaned that I wll use two magnets that and one of them will be connect to rotary axis and for send the signal you will flip the magnet and them instad of pulling the other magnet it will push to other magnet so when the two magnet will be on the same pole the signal will be 1 and if the two magnet will be on different poles the signal will be0

This is a fair, valid experiment. But once you are transferring Energy from one magnet to the other, you have evidence that an EM wave has been launched (fields changing with time) and there will also be Electric Fields involved. A magnet rotating at high enough speed will radiate a wave that is indistinguishable by a distant receiver+antenna from the wave transmitted from a conventional RF transmitter.

As mentioned above, the effect can only be measured if the S/N ratio is high enough. Doing the experiment 'mechanically' would be very challenging. Along the lines of detecting gravity waves.

I don't have to connect it to actuall computer i can connect it to led or something , this is also can be useful as wireless charging

Would you PLEASE start checking your spelling? This has gotten ridiculous. Your incredible sloppiness in posting has been mentioned several times in this thread. Please pay attention and do something about it. Do not hit "post reply" until you have checked your spelling. Thank you.

this is also can be useful as wireless charging

Wireless charging involves the transfer of serious amounts of Power (say a Watt minimum). This would not be practicable with your proposed mechanical system, which would involve microWatt levels. Two different extremes of the same phenomenon.
'Wireless' charging is best described as 'Non-contact' charging. i.e. the device is laid on the dock without being explicitly plugged in. A Power oscillator and two close coupled coils are involved.
