By the way, the untranslated part of page 1 is referring to John Ambrose Fleming’s Right Hand rule.
In the 19th century, John Ambrose Fleming developed the Fleming’s Left Hand rule and the Fleming’s Right Hand rule as a simple way of working out the direction of electric current in an electric generator or the direction of motion in an electric motor. It is important to note that these rules do not determine the magnitude; instead show only the direction of the three parameters (magnetic field, current, force) when the direction of the other two parameters is known.
