Maxwell's first equation is Gauss law
this equation tells us that electric
field lines diverge outward from
positive charges and converge inward to
the negative charges
Maxwell's second equation tells us that
the magnetic field never diverges or
converge they always go around in closed
loops
therefore there doesn't exist a single
magnetic pole Maxwell's third equation
is Faraday's law this equation tells
that electric field lines curl around
changing magnetic fields and that changing magnetic fields include electric fields Maxwell's fourth equation tells that magnetic field lines curl around electric currents and that magnetic field lines curl around changing electric fields.
