Consider this:
A long stream of electrons moves very slowly (0.1mm/s) through space, passing through the ceiling of a room and out through the floor. A stationary observer sits on a chair holding a card with iron filings on it. The card is tapped as the electron stream passes though a hole in its centre, and the iron filings form a circular pattern indicating the presence of circular magnetic lines of force.
The stationary observer says “Yes there is a magnetic field and the evidence is shown by the movement of the iron filings”.
Now, according to special relativity, an observer that moves very slowly with the charge will say there is no magnetic field, because the iron filings on his moving card do not move. So he says “The a magnetic field does not exist”.
According to SR the answer is YES and NO.
Is it not possible that magnetic fields always forms when electrons move through absolute space and that a moving observer’s instrument develops its own field, which prevent it making an absolute measurement, hence only relative measurements are detected.
For a solution for absolute motions of electric and magnetic forces, see:

This solution suggests that magnetic fields always exist when electrons move through absolute space, regardless of an observers relative motion. It is only the motion of the observer that determines whether or not they can be detected.
The simple question is this. Is there a magnetic field in the room? Yes or No?
The answer must be YES.
