In the article «The Lorentz torque experiment», I have proposed an experiment to test the Lorentz force law and the differential Ampere’s force law. The theoretical predictions of the torque on a coil according to the Lorentz force law and the differential Ampere’s force law give different values. The experimental measurement will confirm one law and refute the other. The curve of the Lorentz’ torque and the Ampere’s torque are drawn in the Figure 1.

It is important for the experimenters to know how to do this calculation and why the values are so different. Below is the explanation.
