How Does the Lorentz Force Fit into Classical Electromagnetism?

Click For Summary
SUMMARY

The Lorentz force is a fundamental concept in classical electromagnetism, representing the force experienced by a charged particle moving through an electric field and a magnetic field. It is defined by the Lorentz force equation: F = q (E + v × B), where F is the force, q is the charge, E is the electric field, v is the velocity, and B is the magnetic field. This force is indeed categorized under the electromagnetic force, despite its historical naming. Understanding the Lorentz force is crucial for comprehending the interactions of charged particles in electromagnetic fields.

I thought in classical physics, only four forces account for all mechanics:

1 gravitational attraction
2 electromagnetic force
3 nuclear strong force
4 nuclear weak force

There is also a Lorentz force on a charged particle moving through a magnetic field. How does classical EM account for this force? It does not fall in one of the above categories. I must be missing something important. What?

If you mean what I think you mean, the Lorentz force falls under the electromagnetic force. They just call it the Lorentz force equation for historical reasons. For reference, this is the equation I'm thinking of:
