If these two statements are logical implications of Maxwell's equations, a) A magnet that is not moving with respect to the aether will not have an electric field. b) A magnet that is moving at a constant velocity with respect to the aether will have an electric field. Then consider this thought

The law of Faraday is very clear any change in magnetic flux induces charge hence a field. Many untrained physicists write j (current) instead of q what is wrong. To measure a current you have to cut the ring (rim) of charges what leads to dragging forces and movement of charge over e.g. a

The question of whether the magnetic field rotates in the faraday disc generator is a question that is related to aether theories in particular or any theory of privileged reference frames in general. It got me wondering if there are alternate ways to test for the presence of an aether or a

As most might know, in physics we only know force fields. Thus so called field lines (magnet field) are equipotential cuts of the space covered by fields. Of course you never can draw such a line as all sources are in constant motion/rotation. The static magnetic field is a special case as it

Another visualization of the behaviour of magnetic fields without the concept of lines of force. When the magnet is moved around it simply changes the orientation of all the little compass needles. The notion of lines of force tends to make one think the magnetic field is somehow mechanically

Here is a physical demonstration of the situation using a ferrofluid. https://www.youtube.com/watch?v=Bn41nPOGq-U The ferrofluid does not rotate with the cylindrical magnet, which supports the idea that the magnet's field does not rotate with the magnet. (There is a little bit of movement but the

It depends what you mean by a field. If you imagine the field is made of wire-like filaments which are fastened to an atom then you would expect the field to translate and rotate whenever the atom translates and rotates. On the other hand if you imagine the field is a vector field then the field

Instead of measuring voltages, another approach would be to measure how the entire assembly moves in response to the various relative rotations. In order to observe such effects, the entire assembly should be self contained so that it is free to slide over a level surface. The relative rotation of
