Two conducting wires with electron currents \( \class{blue}{\boldsymbol{I}_1} \) and \( \class{blue}{\boldsymbol{I}_2} \) in the same 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 left-hand rule - \( \class{violet}{\boldsymbol{B}_1} \) points out of the screen. The second wire experiences a Lorentz force \( \class{green}{\boldsymbol{F}_2} \) to the left - towards the first wire.
  • The second wire generates with its current in the same direction, a magnetic field \( \class{violet}{\boldsymbol{B}_2} \) at the location of the first wire. \( \class{violet}{\boldsymbol{B}_2} \) points into the screen. According to the right-hand rule, the first wire experiences a Lorentz force \( \class{green}{\boldsymbol{F}_1} \) to the right - towards the second wire.

The two wires attract each other!
