Does the Lorentz Force Account for Radiation Loss in Charged Particles?

Click For Summary
SUMMARY

The discussion centers on the Lorentz force and its relationship to radiation loss in charged particles. When a charged particle accelerates due to the Lorentz force in electric and magnetic fields, it emits electromagnetic radiation, resulting in energy loss. The concept of radiation reaction force, specifically the Abraham-Lorentz force, is introduced as a necessary modification to the Lorentz force to account for this radiation. However, the application of this force leads to contradictions within Classical Electrodynamics.

PREREQUISITES

when a charge particle is moving in electric and magnetic field, a force exert on this particle is Lorentz force.

when this force apply to this particle, it accelerate and we know accelerated charge particle radiate.

when a particle radiate an electromagnetic wave ( photon ) lose it's energy.

it seems that Lorentz force should be modify to describe particle's radiation!

is it true?

Your line of thought is essentially correct within the framework of Classical Electrodynamics.

The force you are referring to is called radiation reaction force or Abraham-Lorentz force.

However, it leads to many contradictions within Classical Electrodynamics.
