I have a question here about Maxwell's equations: according to faraday's law at some point in space changing magnetic field with time creates the curl of electric field at that point and according to Ampere's law with Maxwell's correction changing with time electric field or electric current density creates the rotor of magnetic field. So those created fields are circular, so it means that they should have no beginning, so if electric field vector changing with time at some point created circular magnetic field at that point, this magnetic field (that was created) should be zero (or infinity, I'm not sure, but the field is not defined) at origin point and exist only around it. The same is if magnetic field induces electric. So if the created circular field is zero at origin point and exists only aroud that point, it means that both electric and magnetic field don't exist at the same point at the same time. So how is with electrmagnetic waves when one field creates another and they both exist at the same point in space, the graphs of functions ( Eosin(wt+kx) and Bosin(wt+kx) ) show that, because they exist at every point ?
