from Wikipedia, the free encyclopedia

The following three effects of physics described by James Prescott Joule are called the Joule effect :

  • The deformation of magnetic substances in a magnetic field, see magnetostriction
  • The first Joule law about the heating by electrical current in electrical conductors, see Stromwärmegesetz
  • The second Joule law about the constancy of the temperature with the expansion of an ideal gas, see Gay-Lussac experiment
