3-Finger-Regel (UVW-Regel)

I was given this wonderful mug with Physics equations on it. I was interested in Fleming's Left Hand Rule. The problem is that it is actually the RIGHT hand. In England, we use the right hand for the generator rule. The left hand is called the motor rule because it is about putting a current in and getting movement out. This is definitely the same rule because of the UVW mnemonic. Ursache is the cause and Wirkung is the effect. Technische Strom is conventional current which goes into the motor, so it is the cause. Kraft is the force - the effect. Richtung means the direction and, if you were wondering, Vermittlung can be translated as "connection". Here's the way I use Fleming's Left Hand Rule:
All that has happened is that the German rule swaps force with current and if you use right hand instead of left, magnetic field will point in the same direction.
