Fucking magnets, how do they work?

They work by the magnetic forces of the Earth, which is caused by the excessive amounts of Iron(Fe) in the Earth's inner core.

all "magnetismem" is simply the effects of general relativity with regards to electrostatic forces

by Helmholtz decomposition, classical gravity must also a gravitational magnetic field, although I don't ever hear people mention it theoretically (of course, it would be very weak). I can't decide if this is true of relativistic gravity too...

that explains jack fucking shit

ken wheeler is a photographer who posts a lot of youtube videos about how all of modern physical theory is wrong and his explanation is correct.

none of it has math or theory backing it up, just handwavy rambling half-explanations

The only consistent theory is the weber force, you know
The poltically incorrect professor who along the gottingen seven was chased out of germany for supporting the german constitution.

Particles act directly according to relative position speed and accelaration,
Look up orahilly, the time delay formulation via speed of light is guage invariant so according to griffths as well the force still points from the present position of the particle

eh, for permanent magnets not so much. electrons have an intrinsic magnetic moment, which is just a quantum mechanical phenomenon. relativity only plays a role in electromagnets really
