Looking at the fields that result from a uniformly moving electric charge, derived from the Lienard-Wiechert potentials, you find that an observer at a right angle to the direction of travel will see a magnetic field proportional to ##\beta (1 - \beta^2)## suggesting a maximum field at ##\beta = 1/\sqrt 3##.(adsbygoogle = window.adsbygoogle || []).push({});

Can someone help me understand on an intuitive level why it doesn't continue to increase with velocity?
