Maxwell's Relations of Thermodynamic Functions

AI Thread Summary
Maxwell's Relations are indeed expressed as the derivatives of thermodynamic functions, specifically relating entropy, volume, pressure, and temperature. The two relations provided are correct, but they are not exhaustive; there are additional Maxwell's Relations derived from different thermodynamic potentials. Thermodynamic potentials, such as Helmholtz and Gibbs free energy, are often referred to as thermodynamic functions. Clarification on terminology is important, as different texts may use varying notations that can cause confusion. Understanding these relationships is crucial for mastering thermodynamics.

The following are Maxwell's Relations right?

\left(\frac{\partial s}{\partial v}\right)_{T} = \left(\frac{\partial p}{\partial T}\right)_{v}

\left(\frac{\partial s}{\partial p}\right)_{T} = - \left(\frac{\partial v}{\partial T}\right)_{p}

Are these all? And BTW, these are derived from the thermodynamic POTENTIALS. Are thermodynamic POTENTIALS also called thermodynamic FUNCTIONS? Sorry for this dumb question. I just want to be sure. I'm reviewing and all the different notations from different books are really mixing up in my head.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
