2.3.1. Force action on cur rent-carrying conductors
A current-carrying conductor is enclosed by a magnetic field. If this conductor is entered into a magnetic field, the individual fields are superimposed.
(1) Basic presentation of the superimposing fields
On the one hand there is magnetic flow boosting. Conversely, one encounters magnetic flow fading.
A current-carrying conductor is pushed away from the external magnetic field towards the weaker field side.
Left hand rule (motor rule)
If the left hand is positioned thus in a magnetic field so that the field lines enter the palm of the hand and the projected four fingers are directed towards the conductor current, then the extended thumb points in force direction towards the conductor.

Electrodynamic law of force
Force is yielded through the following equation:
F = B • l • I • N
