Tony,

 

No, that’s just a simple experiment one can do if one wishes, in the lab. Actually such experimental measurements of the growth of the fields and potentials from a sudden source charge are all over, but usually never addressed as “just that” for the purpose of establishing the fields.

 

Cheers,

Tom

The para. that I have outlined in red - is this the lab experiment that got Lee and Yang their Nobel prizes?

He doesn’t mention that you can suddenly produce a dipole (magnetic or otherwise) at a point in the lab, and with your instruments pre-placed on a radial line away from that point, you can directly measure the speed of light flow of those photons pouring from that magnet. Hey! If they’re sitting still, then the field could never be established in the first place

Thanks

Tony
