# Illustration Repulsive Lorentz force - two conductors with current flowing in opposite directions

Two conducting wires in which the electron currents $$\class{blue}{\boldsymbol{I}_1}$$ and $$\class{blue}{\boldsymbol{I}_2}$$ flow in opposite directions. Both currents generate a magnetic field in the whole surrounding space.
• The first wire generates a magnetic field $$\class{violet}{\boldsymbol{B}_1}$$ at the location of the second wire and - according to the Right-hand rule - $$\class{violet}{\boldsymbol{B}_1}$$ points out of the screen. The second conductor experiences a Lorentz force $$\class{green}{\boldsymbol{F}_2}$$ to the right - away from the first wire.
• The second wire generates with its opposite current a magnetic field $$\class{violet}{\boldsymbol{B}_2}$$ at the position of the first wire and - according to the Right-hand rule - $$\class{violet}{\boldsymbol{B}_2}$$ also points out of the screen. The first wire experiences a Lorentz force $$\class{green}{\boldsymbol{F}_1}$$ to the left - away from the second wire.
