Newton's 3rd Law and electric charges

bgq · Jan 14, 2014

Hi,

Is Newton's 3rd law applicable to electric charges?

I have a problem with a situation where two identical positive charges moving perpendicular to each other. The magnetic forces exerted by each one on the other have same magnitude but their directions are not opposite.

NIII does not hold for moving charges. The momentum of the electromagnetic fields changes for two moving charges, so the sum of their mechanical momentum is not conserved.
