In cases where the rotational of the magnetic field H is zero, we can define this field as the gradient of a scalar function defined as the magnetic scalar potential (similar to the electric potential). What is the physical meaning of this magnitude?
Your question touches on a significant aspect of electromagnetic theory. The magnetic vector potential A is often viewed as an abstract quantity that simplifies the solution of Maxwell's equations. However, James Clerk Maxwell himself saw deeper physical meaning in it. Maxwell proposed that the magnetic vector potential A could be interpreted as "momentum per unit charge." This interpretation aligns with his broader work in unifying electricity and magnetism, showing that electric and magnetic fields are different manifestations of the same phenomenon.
Hi, Preston Guynn
Thank you very much for recommending the article
Dear, Zhigang Pu
Thank you very much for your explanation of the physical meaning of the potential vector A, which was enlightening. However, I believe you were confused by my question, in fact I am trying to know more about the physical meaning of the magnetic scalar potential (\phi_{m}) (the one similar to the electrical scalar potential).
In any case, thank you very much for your willingness to answer my question.
A = em FiV, Here A - the vector potential, em - the two EM constants, Fi - the scalar potential, as the pressure in the medium,
V - the speed of this quantity. The divergence of this equality gives the condition of L. Lorentz. The magnetic scalar potential is an artificial conditional quantity, understanding free magnetic poles.
