安家右手拳法指的是安培右手螺旋定则,即:四指与螺线管中电流环绕的方向一致握住螺线管,伸出大拇指为通电螺线管的N极.从定则中可以看出我们最终要右手握拳,故我称之为安家右手拳法,同时我们也可以看出通电螺线管的三要素:电流方向、绕法(两者可合称为电流的环绕方向)、极性.由此可以有安家右 The right hand boxing refers to the ampere-right helix rule, ie, the four fingers are in the same direction as the current in the solenoid, holding the solenoid thumbs up to the north pole of the solenoid, and from the rules We can see that we are going to make a right-hand fist in the end. Therefore, I call it the right hand boxing method. At the same time, we can also see that the three elements of the solenoid are current direction, winding method (both can be collectively referred to as the current surrounding direction) So you can get home right
