Is this blokes Maths correct? He's beyond my pay grade.

Yes, i talked about it in the very previous thread. There is no evidence that a changing electrostatic field induces a magnetic field. Otherwise we had motors made of only  permanent magnets and capacitors, but no one has measured such magnetic fields at  capacitors. Also electrostatic field doesn't change only in capacitors, it changes also for example when one object charges another, without being in contact with it. No current flows then, and no one has measured any magnetic field when such change happens.

It is only experimentally confirmed that magnetic field is induced by a current. When there is a current, an electrostatic field changes in a certain orderly way, but it is only a certain kind of change of the electrostatic field, not every change.

It seems that radio waves are really a changing magnetic field, changes in the magnetic field spreading with the speed of light. Somewhere i read that even Maxwell himself once suggested that. Thus just a magnetic induction, which is known to happen over a distance. So one may as well say that Faraday discovered it. Not entirely so, because when it reflects and such, there may be currents involved. And some things we have been taught are just someone's fantasy. But then it may be thought that a fantasy of these who are more important than us, should be good enough to be reality for us.
