The Voice of Allan Zade
The article ‘Human Illusion of Field’ (ref. # 1) explains one of the most significant illusions that mislead the human mind in the case of an “electrically neutral body.” That article explains the problem regarding the static location of the body and the measuring instrument. It is time to discuss those processes in dynamics.
Suppose the observer moves the body in a given direction (CA-F1) and tries to detect a difference in measurements. The following figure shows that case.
Figure 1. Field dynamics in case of a moving body
There is one more old question here. The body initially exists at one point (CA). However, the body's field appears at all other points located at any distance from the body. What does it mean? It means this: Something supports the propagation of the field from the body to any other point. That thing is usually referenced as a continuum.
Continuum supports the propagation of any disturbance from a given point to any other continuum point.

Therefore, the continuum supports the propagation of fields as a form of disturbance. Field means disturbance of the continuum. Disturbance at any point of the continuum causes the following disturbance at other points of the continuum located close to the first point. That process of step-by-step disturbance propagation allows the continuum to spread any disturbance in any direction.
Moreover, disturbance propagation has some duration. Therefore, disturbance covers any distance between any given points of the continuum by some duration (including any two points located at a tiny distance from each other). That duration creates some limitations in the speed of disturbance propagation. In other words, disturbance never goes by itself or through free space. It propagates only through interaction with the continuum.
It is time to come back to the figure shown above. Suppose now this. The body C moves toward point F1. It starts motion at the point CA or the point of its initial location. As soon as the body begins its motion, disturbance made by the field starts propagation at any direction from the point CA. In other words, it makes some wave of disturbance. In the case of an isotropic medium, the disturbance has an equal propagation speed in any direction. Therefore, field disturbance and the body make motion in a continuum independently of each other.
The process of body motion and field propagation takes some duration. As a result, the body covers the distance CA-CB, and the field disturbance covers some distance in the continuum, forming a spherical surface with radius CA-F1 (shown in the figure as the dashed circle).
That condition means this: In the case of a body's motionless location, the field disturbance keeps an equal distance from the body because the body does not move concerning the continuum. In the case of a moving body, the situation changes dramatically, and different points of disturbance appear at varying distances from the body.
For example, distance CB-F1 becomes the minimal distance between the body and the disturbance. All other points maintain a considerable distance (F3, F4, etc.). Distance CB-F2 becomes the highest because the direction of disturbance propagation and body motion are opposite.
There is one more aspect here. As explained in the article' Human Illusion of Field' (ref. # 1), the observer has no measuring instrument to detect any changes in the medium (by field measurement) in that case. Therefore, the observer falls under the illusion that the moving body also "has no field around it."
Suppose now this. The observer changes the charge of the body and conducts the experiment again. In that case, he detected some differences in the readings of the measuring instrument. In other words, that instrument shows equal readings at points F1 and F2 for the statically located body CA. Moreover, those points are equidistant from the body CA.
The situation changes significantly for a moving body. In that case, the same measuring instrument shows equal readings at points F1 and F2. However, the distance between the body and the measuring instrument CB-F1 becomes unequal to CB-F2. Moreover, the measuring instrument keeps equal readings from the moving body at different distances. Those points also have unequal distances from the moving body CB. For example, the distance of CB-F3 is less than the distance of CB-F4. However, the measuring instrument shows equal readings at those points, too. Therefore,
The medium disturbance covers an equal distance in any direction in any given duration of disturbance propagation.
In the case of a moving body, the distance between the body and equally disturbed points of the continuum depends on the direction of body-to-continuum relative motion.

Hygens' principle is a particular case of the first statement (ref. #2).
Is it possible to conduct an experiment that shows that phenomenon in the lab? Yes, it is. The problem comes from the experiment's mechanical nature. A researcher can use a rotating wheel to keep the body and the measuring instrument in continuous motion in the lab because it would be impossible to extend a lab to a distance suitable for that measurement in case of a linear motion of the body and the measuring instrument.
Some information about such experiments comes from the labs. However, you cannot find it in any "mainstream journals" publications because such information falls into the "forbidden area" of knowledge.
