Travelling along a \(B\) field line, looking forwards at some point on the line ahead, the \(E\) field radiates outwards. Once we pass that point and look backwards, \(E\) immediately radiates inwards. We have a very thin phenomenon, a manifestation lacking in the third dimension. A 2D entity.
If we now move along the path of the charge producing the magnetic field, which is perpendicular to the \(B\) field line, we find that it is consistent when the charge itself is very flat, along the direction perpendicular to its velocity.
This could be the true shape of the electron previously modeled as point charge, a 2D body.
