The previous post assumes that the negative end of the dipole is spinning and establishes a directional sense of the B-field. What is interesting is to imagine the positive end spinning.
E field in this case is in the negative \(x\) direction. The positive charge, in a spin, exert less pull on the negative charge than the applied E-field. The dipole is moving right. And the B field so created is, by the right hand rule,
where y is in the clockwise sense. The first thing to notice is that the direction of E-field and B-field is consistent with that of electromagnetic wave, where \(E \times B\) = direction of wave propagation. However, this setup violates Lenz's Law. The E-field cuts the B-field as the charge moves, produces a force by the left hand rule, that is in the same direction as the direction of travel of the positive charge. That means the charge is accelerated further in the same direction.
This may be the situation we are looking for in which photons achieve light speed. This is a consistent picture of photons being dipoles on helical path. Added to the big picture is a spinning positive charge; the dipole is moving opposite to the applied E-field; and a mechanism to achieve terminal velocity, in free space, light speed.
What is lacking is a light-mass positive charge. A positron may be, of mass less than an electron, to form a dipole with a heavier-mass negative charge. That would be a marriage of light and magic.
