$F = q \cdot v \cdot B \cdot \sin ∢ (\vec{v}; \vec{B})$

$F = I \cdot l \cdot B \cdot \sin ∢ (\vec{l}; \vec{B})$

$B = \frac{μ_{0} μ_{r} \cdot I}{2 π \cdot r}$

$B = \frac{μ_{0} μ_{r} \cdot I}{2 \cdot r}$

$B = μ_{0} μ_{r} \frac{n \cdot I}{l}$

$Φ = B \cdot S \cdot \cos ∢ (\vec{B}; \vec{S})$

$ε = - \frac{Δ Φ}{Δ t}$

$ε = - L \frac{Δ I}{Δ t}$

$ε = n \cdot B \cdot S \cdot ω \cdot \sin (ω t + φ)$

$U_{sk} = \frac{U_{max}}{\sqrt{2}}$ $I_{sk} = \frac{I_{max}}{\sqrt{2}}$

$\frac{U_{1}}{U_{2}} = \frac{n_{1}}{n_{2}} = \frac{I_{2}}{I_{1}}$
