Magnetfeldkreis
Magnetfeldkreis is a descriptive term used in German-language physics to refer to the circular arrangement of magnetic field lines around magnetic sources such as electric currents or moving charges. The concept emphasizes the circular, closed nature of magnetic field lines, which form continuous loops rather than having beginning or end points.
A classic example is the magnetic field produced by a long straight current-carrying wire. The magnetic field
The idea of a magnetfeldkreis is consistent with the fundamental property of magnetic fields: there are no
In materials, microscopic currents due to electron motion and magnetization generate similar closed-field patterns, though the
Overall, the magnetfeldkreis highlights the circular, continuous nature of magnetic fields as understood in classical electromagnetism.
