Several parallel conductors are projecting out of the plane. \\
The same current $|I|$ flows through all the conductors in different directions (see image below). \\
Sketch at least 10 field lines of the magnetic field strength $\vec{H}$ in such a way that the different properties of the field lines (e.g. direction and density) can be seen.

  * high density of field lines near the conductors
  * direction of the field lines given by the right-hand rule
  * magnetic field has closed field lines
  * resulting field given by superposition of field lines
