Formulas

B = \frac{F _{m}}{I l}

B = Fₘ / (Il)

Φ = B S cos α

Φ = BS cos α

F_{A} = I l B sin α

Fₐ = IlB sin α

F_{L} = q v B sin α

Fl = qvB sin α

NOTATION

$B$: Magnetic induction is a force characteristic of a magnetic field.
$F_m$: Magnetic force is the force of a magnetic field on a current-carrying conductor.
$I$: Current strength is the charge passing through the cross section of a conductor per unit time.
$l$: Conductor length is the length of the conductor section under consideration.
$\Phi$: Magnetic flux is a measure of the magnetic field passing through a surface.
$S$: Area is the size of a surface or cross section.
$\alpha$: Angle is a quantity characterizing the mutual rotation of directions.
$F_A$: Ampere force is the force of a magnetic field on a current-carrying conductor.
$F_{\text{L}}$: The Lorentz force is a force acting on a moving charge in a magnetic field.
$q$: Electric charge is a quantity that determines the participation of a body in electrical interaction.
$v$: Speed is the speed and direction of change in body position.
