Stefan-Boltzmann law (Stefan, L. Boltzmann):
The radiated power P (it is rate of emission of electromagnetic energy) of hot body is proportional to the radiating surface area, A, & the fourth power of the thermodynamic temperature, T. The constant of proportionality refer to the Stefan-Boltzmann constant. Mathematically specking,
P = e sigma A T4,
Where the efficiency rating e refer to the emissivity of the object.
Biot-Savart law (J.B. Biot, F. Savart) A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically spec
