A conducting wire in a magnetic field \( \class{violet}{B} \) carries an electric current \( I \), which points perpendicular to the current direction (into the screen plane). Thus, a magnetic force \( \class{green}{F} \) (magnetic part of the Lorentz force) acts on the current-carrying wire, which deflects the wire - according to the left-hand rule - to the right.
