Does Newton's Third Law apply to magnetism?

AI Thread Summary
Newton's Third Law, which states that every action has an equal and opposite reaction, applies to magnetism in the context of moving charges. When a moving charge creates a magnetic field that exerts a force on another charge, the second charge exerts an equal and opposite magnetic force on the first charge. This interaction can be understood through the relative velocities of the charges, which are equal in magnitude but opposite in direction. The magnetic force experienced by each charge is proportional to their velocities. Thus, the principles of Newton's Third Law are indeed relevant to magnetic interactions.

Newton's Third Law states that every action has an equal and opposite reaction. I'm wondering if and how this applies to magnetism. I would assume that it would mean if a moving charge is creating a magnetic field that causes a magnetic force on another charge, then it can be said that the latter charge causes a magnetic force on the former charge of equal magnitude but opposite direction? I suppose this can be explained from the fact that the relative velocities of each charge is equal in magnitude and opposite in direction of each other, and the magnetic force is proportional to the velocity.

Yes.

Right!
