NOTATION

: Magnetic flux is a measure of the magnetic field passing through a surface.
: Magnetic induction is a force characteristic of a magnetic field.
: Area is the size of a surface or cross section.
: Angle is a quantity characterizing the mutual rotation of directions.
: Inductance is the ability of a conductor to create a magnetic field when current passes.
: Current strength is the charge passing through the cross section of a conductor per unit time.
: The electromotive force of induction is the action of a vortex electric field in a circuit.
: The number of turns is the number of turns of conductor in the coil.
: Magnetic flux change is the amount of change in magnetic field flux.
: Time interval - the duration of the process under consideration.
: Magnetic field energy is the energy stored in a magnetic field.
