What? No you can't. The fields are invariant under gauge transformations.
- ThePhysicist 3y agoYou're right, sorry I was thinking of a Lorentz transformation that would make either the magnetic or electric field disappear under certain conditions.
- wch4999 3y ago"transform into each other" would be more appropriate. The gauge choice you mentioned is not totally wrong. The gauge freedom can be used to set the electric field to zero, but only once at a single point.
- toth 3y agoSorry, but gauge transformations do not (by construction) affect the physical fields at all. You cannot set E to 0, even at a point, with a gauge transformation.
