Radio waves

[YT2095]

I`m sure most are aware of the EM (Electro Magnetic) Spectrum.
radio waves start where sound stops (roughly 30Khz).
Radio waves depend on a magnetic feild fluctuation (as does all phenomenon in the EM spectrum).
IF a fixed magnet where to be rotated or physicaly moved at a rate of 30Khz or greater, would it broadcast a carrier wave?

Edit: to aviod confusion as to my question, I`ll try a restate;
If a permanent magnet were to vibrate at 30Khz or above, would it emit R.F (radio frequency) ?

Are you meaning to modulate a simple sine wave on a carrier wave???

[YT2095]

not to modulate, as that would involve side oscilations on the 30khz+ freq.

I just mean the carrier, a constant signal being transmitted with no sub signals on the wave :)

To create an electromagnetic wave you have to accelerate a electric charge.

It starts from 0Hz to ?infinity?Hz

But it only starts to travel in air/vacuum if the frequency is high.

So the answer would be Yes it will generate an elektromagnetic wave.
(if you will be able to detect it is an other question.)

[YT2095]

well hypotheticly then, if a permanent magnet were to Vibrate against another magnetic feild at say,,, 150Khz a simple LongWave radio receiver should be able to pick it up as a dead carrier (a quiet space, with no white noise as on unused or between station frequencies).
that`s more or less what I though as well, I just wanted some confirmation of this :)

although ANYMORE input from those in this area of science would be welcome! :)

an incredibly weak one!

[YT2095]

why do you say weak?
