Fleming's Right Hand Rule

right hand rule


Is a method for determining vector directions, and is based on the Cartesian planes.
It is used in two ways: to address vector and linear movements and movements and rotational directions.

In electromagnetism, the right hand rule states that if extends his right hand on the driver as the outstretched fingers follow the direction of the current, the thumb at right angles to the fingers indicate the direction of movement of the pole north of a magnetic needle.

The field created by the electric current through a straight conductor as any magnetic field, is composed of lines which are arranged in the form of concentric circles arranged in planes perpendicular to the conductor.

Thus, when rotating a corkscrew or screw "to the right" (in the sense of the hands of a clock) or screw corkscrew "advances" and vice versa, when rotated a corkscrew or screw "to the left "(as opposed to clockwise) or screw corkscrew" retreat ".
