:::::::::: Yes, electromagnetism does involve particles moving close enough to the speed of light for relativistic effects to be important. Examples include the electron gun in an ordinary CRT TV set, electric motors, speakers, and just about any electronic device. These are not new. The earliest non-optical tests of special relativity were the Kaufmann–Bucherer–Neumann experiments.[http://en.wikipedia.org/wiki/Kaufmann%E2%80%93Bucherer%E2%80%93Neumann_experiments] They started in 1901 based on Lorentz's relativity, and pre-date Einstein. They show that mass increases with velocity so that nothing goes faster than light. In Newtonian mechanics, the speed of light is not an obstacle.
