KEY CONNECTIONS

Formulas

Φ = B S cos α

Φ = BS cos α

Φ = L I

Φ = LI

E_{i} = n \frac{∣ ΔΦ ∣}{Δ t}

εᵢ = n|ΔΦ| / Δt

W = \frac{Φ I}{2}

W = ΦI / 2

NOTATION

$\Phi$: Magnetic flux is a measure of the magnetic field passing through a surface.
$B$: Magnetic induction is a force characteristic of a magnetic field.
$S$: Area is the size of a surface or cross section.
$\alpha$: Angle is a quantity characterizing the mutual rotation of directions.
$L$: Inductance is the ability of a conductor to create a magnetic field when current passes.
$I$: Current strength is the charge passing through the cross section of a conductor per unit time.
$\mathcal{E}_i$: The electromotive force of induction is the action of a vortex electric field in a circuit.
$n$: The number of turns is the number of turns of conductor in the coil.
$\Delta\Phi$: Magnetic flux change is the amount of change in magnetic field flux.
$\Delta t$: Time interval - the duration of the process under consideration.
$W$: Magnetic field energy is the energy stored in a magnetic field.
