The following setup shall be given:
Four conductors are located perpendicular to the plane of the diagram
All of them conduct a current with the same magnitude, but not in the same direction.
A permanent magnet is located in between the conductors.
1. Do not consider the permanent magnet at first. Draw at least 10 field lines of the H-field qualitatively.
Give a a correct representation of their direction, and density for the shown area.
Result
2. Discuss how the permanent magnet affects the H-field, based on the fundamental definition of the H-field.
Result
The H-field is defined by currents $\sum I = \int H {\rm d}s$ .
In the permanent magnet, there are no free currents.
The bound currents (of the permanent magnet) create also an H field.
This exits on the north pole and enters the magnet on the south pole (similar to the B-field)_
$H = B/\mu$
The H-field from task 1 gets distracted
