| Jan 26, 2021 at 22:43 | comment | added | Jus12 | So is it safe to say that energy is more densely packed in the magnetic component? | |
| Jul 30, 2014 at 1:09 | comment | added | dmckee --- ex-moderator kitten | Of course @Emilio is right, but interestingly the size of the difference in the forces is a function of the mass of the particle, not it's charge. If we were to imagine a very low mass test particle--say a charged neutrino (!)--then the difference gets to be much smaller | |
| Jul 29, 2014 at 19:54 | comment | added | Emilio Pisanty | Looking at it in terms of energies can be misleading, sometimes by quite a bit. If you set a charged particle to oscillate driven by the electric and magnetic fields of a plane wave, then the electric component of the Lorentz force will be vastly bigger than the magnetic part. | |
