I have seen these relativistic calculations for electrostatic
charge and magnetic fields.  The presentations I saw produce the
wrong unit for magnetic field.  If the equation produces the
wrong unit for magnetic field, then it would seem that the theory
is a failure.  Can you provide a link or precise equations for
calculating a relativistic magnetic field from electrostatic
charge so we can see whether the equation is correct or not?  I
can't find the web page I saw this on.
