What’s the difference between Maxwell’s equations and Maxwell’s relations?

Maxwell’s equations are fundamental tools for electric and magnetic fields, while Maxwell’s relations focus on thermodynamic quantities like temperature, pressure, volume, and entropy. For more on Maxwell’s equations, see “What are the fundamentals of Maxwell’s equations and how do they relate to TENGs?” Maxwell’s relations give designers a powerful tool for analyzing thermodynamic systems like internal combustion engines or data center cooling.…
