Magnetic field of current. Ampère force, Lorentz force. Charged particle motion in B

Section Electrodynamics (continued) — grade 11, section 1. In grade 10 you studied electrostatics ( $\vec{E}$ , $\varphi$ , $C = Q/U$ ) and direct current ( $I = U/R$ , Ohm's law for a complete circuit). Here — the magnetic field of steady current and forces on conductors and charges in $\vec{B}$ .
