Re: Challenging magnetic experiments

Interesting concept. However, the postulated lag of the accelerating magnetic field would require that there be a compliance (spring) between the field's mass and that of the permanent magnet, and that this compliance creates a larger phase lag than that produced by the flexure of the permanent magnet structure itself (as it accelerates). This mechanical flexure of the permanent magnet during acceleration would also produce a lag of the type postulated.

Another difficulty relates to the laser. If the magnetic field has mass (related to its energy), the photons from the laser most certainly have mass (already well demonstrated with solar "windmills" common in curio shops). So the light sensed near the magnetometer will also demonstrate a lag. This must be compensated for in the measurements.

A last difficulty relates to eddy currents which will be set up in nearby conducting objects when the magnetic field starts to move. These eddy currents will tend to oppose the changes in field, and therefore will appear to produce a lag in the magnetic field relative to the position of the magnet. Admittedly, however, this lag will reach and remain at a maximum as the magnet achieves constant angular velocity. This latter fact might permit eddy currents to be compensated for.
