The phenomenon of self-induction is the occurrence of an induced field in a circuit as a result of a change in the current in this circuit.
Magnetic substances are all substances capable of being magnetized in an external magnetic field, i.e. create a (internal) magnetic field of the substance itself.
Diamagnets are substances in which atoms or molecules do not have magnetic moments in the absence of an external magnetic field. The atoms of such substances are called diamagnetic atoms.
Atoms (or molecules) possessing a certain magnetic moment are called paramagnetic, and the substances consisting of them are paramagnetic.
Ferromagnets are a group of substances in a solid crystalline state, which has a set of magnetic properties due to a special interaction of atomic carriers of magnetism.
The magnetic hysteresis of a ferromagnet is the lag of the change in the magnetization of a ferromagnetic substance from the change in the external magnetic field in which the substance is located.
Ferromagnets with a wide hysteresis loop are called hard magnetic materials (carbonaceous, tungsten, chromium, aluminum-nickel and other steels).
Absolutely white surface - surface reflecting completely all beams, falling on it(her).
Absolutely black surface a surface absorbing all beams, falling on it(her).
Absolute pressure (Р) - pressure counted from absolute zero of pressure or from absolute vacuum. This pressure is thermodynamic parameter of a condition.
The additive (extensive) parameters - parameters, which meaning(importance) are proportional to weight of system (Volume, energy, энтропия etc.).
Адиабатная- (теплоизолированная) system the system has адиабатную an environment, which excludes an exchange of heat (heat exchange) with an environment.
At the moment of evaporation- of last drop of a liquid in the limited space without change of temperature and pressure is formed dry sated of pairs. The condition such pair is defined(determined) in one parameter - pressure.
