Embodiment Construction

[0008] Such as figure 1 As shown, extend the right hand so that the four fingers and the thumb are on the same plane, the thumb is perpendicular to the four fingers, and the four fingers point to the magnetic field (1) direction, that is, the direction of the magnetic field lines, and the thumb points to the current (2) direction, see figure 1 (a); Then bend the four fingers and the direction perpendicular to the palm is the force of the magnetic field on the current (3) direction, see figure 1 (b).

[0009] Such as figure 2 As shown, extend the right hand so that the four fingers and the thumb are on the same plane, the thumb is perpendicular to the four fingers, and the four fingers point to the magnetic field (1) The direction of the direction, that is, the direction of the magnetic force lines, the thumb points to the conductor movement (4) direction, see figure 2 (a); Then bend the direction pointed by the four fingers and the palm vertically, that is, the i...

Abstract

The invention provides a new right hand rule for replacing Fleming left hand rule and Fleming right hand rule, and the rule is characterized in that right hand flat extends so that the thumb is perpendicular to the other four fingers; the four fingers point to the orientation of magnetic field*; the thumb points to the orientation of known vector (*or *); and the orientation which is pointed by the four fingers which are bent to be perpendicular to the palm is the orientation of the required vector (*or *). The Fleming left hand rule and Fleming right hand rule which are learned in the high school are easily confused and difficult to be applied, in order to be convenient for memory and orientation decision for the students, the new right hand rule is designed, which can judge the acting force of magnetic field applied to electric current and the orientation of the electric current produced by lead in the magnetic field simultaneously, is easy to be memorized and operated, and has strong practicability.

Description

technical field [0001] A new right-hand rule of the invention replaces the left-hand and right-hand rules of Folaiming, relates to the basic rules of electromagnetism, and is an improvement on the left-hand and right-hand rules of Folaiming. Background technique [0002] Originally, in high school physics about electromagnetic induction, to determine the direction of the force of the magnetic field on the current, Fleming's left-hand rule should be used; while the direction of the induced current generated when the conductor cuts the magnetic field line, the direction of the induced current should be used Fleming right-hand rule to determine. This kind of left and right hand rule is easy to confuse, and sometimes it is necessary to twist the hand to determine its direction. When the author was in high school, he discovered its flaws and improved a new right-hand rule to replace Fleming's left-hand and right-hand rule. Contents of the invention [0003] The purpose of the...
