Do the positive and negative parts of electomagnetic wave represents attraction/repulsion of a distant charge?

I'm absolute beginner at physics and try to build intuition by reading the Feynman lectures on physics.

First, I assume - if I understand well - that electromagnetic wave could be produced by a single oscillating charge (doesn't require dipole).

Second, positive and negative electric fields are corresponding to the potential force to be applied to a distant charge (attraction/repulsion).

My question is, if an oscillating charge generated an electromagnetic wave, does a distant charge "feels" attraction due to the positive part of the wave and repulsion due to the negative part of the wave?

• It's the acceleration of the charge that generates the EM wave. Oscillation inherently involves changes in direction and therefore involve acceleration. So oscillation is not necessary. Acceleration is. With that in mind you can see the mental model in the second image doesn't make any sense. Furthermore, another reason the second diagram doesn't work is nothing is physically distinct between up/positive or down/negative to ascribe attraction and repulsion. They're just opposite, but arbitrary directions. Rotate everything around the axis of travel by 45 or 90 degrees What then? Sep 14, 2022 at 20:59
• Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.
