Two moving charged particles exert forces on each other because each one creates a magnetic field in which the other moves. The magnetic field B at r created by a charged particle q at r with velocity v is given by Hog1 V (r-r) 4 r-r B (r): where is the physical constant known as permeability of vacuum. Are the forces between two moving charges, q and 92, obeying Newton's third law? If not, find the condition for which Newton's third law is still obeyed.
