both. when the current is high in the center it is creating a stronger
magnetic field, and when that current reaches the end it creates the
highest voltage so makes more electric field... both are part of the
electro-magnetic wave.


It is not Maxwell model. In it current create magnetic field and THIS
field create the electric field. AND SO ON.


ah, you believe 'and so on'?? the 'so on' means the changing electric field
creates a magnetic field... both conditions are required for electromagnetic
propagation. without the time varying displacement current there would be
no propagation. so yes, you can create a magnetic field from the time
varying electric field.


Your (engineering people) model is O.K. but it is quite different from the
Maxwell model. This is the reason that Art can wrote: " "For your
information you have never built an antenna that conforms in its
entirety to Maxwell';s laws thus you cannot possibly understand
radiation as presented by Maxwell."


the maxwell equations completely describe radiation from an antenna, so all
antennas, even arts, 'conform' to the maxwell equations.
