It can appear like that when you have one particle, but if you take two charged particles moving at different speeds, there won't be a reference frame that gets rid of both magnetic fields.
- drdeca 4y agoCan you have a relativistic theory which has an electrostatic interaction without the theory also having magnetism? If not, I, don’t see what’s wrong with their claim?
- consilient 4y agoA rough equivalent: "momentum is 'just' the relativistic correction to energy between masses observed in different relativistic frames of reference". It might be vaguely trueish if we're very generous in interpreting the "just", but it's absolutely the wrong way to think about things. The electromagnetic field tensor is the real object here. The electric and magnetic fields are artifacts of a particular choice of coordinate system.
