AM Audio Tone...

AM Tone...
We know that computer equipment
emits electromagnetic waves as a byproduct of their current loops.
This is no surprise.
What was surprising was an audio tone
apparently generated by my phone's camera.
I then noted that tones appeared
when I visited some of my pages,
but not others...
Finally, I attempted to duplicate the
Tone phenomenon for my friend Eric,
and the Camera was radio-silent...!
Selective tones...
Hmmm ....
The Gif at the top of this page demonstrates the strength of the tiny
Speaker magnet in an inexpensive earbud.
