KEY CONNECTIONS

Formulas

B=\frac{F_m}{Il}B = Fₘ / (Il)

\Phi=BS\cos\alphaΦ = BS cos α

F_A=IlB\sin\alphaFₐ = IlB sin α

F_{\text{Л}}=|q|vB\sin\alphaFл = |q|vB 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{Л}}: 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: Velocity is the rate and direction of change of a body's position.
