所以,在地球上,我们身体上的正电 荷总是被向下吸引,朝向
地球,而负电荷则会被吸引到上方的 空气中。
这种现象在向下的区域产生了一个 微弱的力,因为一旦我们离开
地面,我们就会开始被周围的空气带 上正电,并被推向
地面的负电。
这就是静电加速。
有人可能会认为来自上方和下方的 吸引力会完全抵消,但是
正是静电梯度创造了从上方正电向 下方负电的
流动。
把地球想象成一个扁平的滤网,上方 有源源不断的水流,
移动得非常缓慢,始终向下方施加一 个力。
这将被视为一个矢量。
随着你从地面上升,静电电势差会不 断增强,从而保持
来自上方的持续压力,直到它到达上 方的高斯面。
当我们反转电场的极性,并将负电表 面置于
正电表面之上时,我们就能反转这种 静电现象,让物体吸附在
上方的极板上,就像吸附在地面上一 样。
这适用于所有类型的物质,你可以移 动木材、铁屑,甚至人类的头发
利用这些力。
信不信由你,你甚至可以让水流弯曲 。
如果两个高斯面之间产生的矢量线 是弯曲的,所有的物质
也将沿着这些场线运动。
在这次演示中,我没有使用扁平的平 面,而是使用两个圆形物体作为
我的高斯面。
你可以看到,在我转动轮子使水晃动 之后, 当水静止下来时
在范德格拉夫起电机上,水面静止时 呈现出一条曲线, 这条曲线顺着
两个球体之间的电场线分布。
这就是为什么电离层— —一个从未在实验室中被创造出来的现象—— 仍然是一个有待证实的理论
但要在地球上创造出这种现象,却需 要这个理论。
麦克斯韦本人修改了安培定律,该定 律曾明确指出, 在没有物质的情况下,静电
场是无法存在的。
麦克斯韦在没有任何科学依据的情 况下修改了它, 使其能够神奇地在我们头顶上的
自由空间中聚集。
密度和电势是密不可分的。
物体的密度越大,它能容纳的电势就 越多。
倒不是我相信原子模型,但即使是元 素周期表也有所区分,
区分了不同元素中所含电势的多少。
在本次演示中,我将金属纽扣挂在氦 气球上,气球使
纽扣保持悬浮在紧贴地面的上方。
仅仅通过增加纽扣的静电势,你可以 看到它会显得更重,
并迫使该悬浮物体沿着静电
势差产生的矢量线向下移动。
在不改变介质或物体密度的情况下, 人们可以改变物体的整体重量
或是物体的重力。

So, here on Earth, the positive charge on our bodies is always attracted down towards the Earth, and the negative will be attracted to the air above. This phenomena creates a slight force in that downward sector, because as soon as we leave the ground, we start becoming positively charged by the air around us, and are now forced towards the negative of the ground.
This is electrostatic acceleration. One might think that the attraction from above and below would cancel out completely, but it is the electrostatic gradient that creates a flow from the positive above to the negative below. Think of the Earth as a flat strainer, and there is a constant flow of water from above,
moving very slowly, always applying a force in a downward direction. This would be considered a vector. The electrostatic potential difference getting stronger as you rise from the Earth will keep a steady pressure from above at all times, until it reaches the Gaussian surface above. When we reverse the polarity of the electric field, and put a negative surface above a
positive one, we can reverse this electrostatic phenomenon, and get things to stick to the upper plate as if it were the ground. This works with all types of matter, you can move wood, iron filings, and even human hair with these forces. Believe it or not, you can even get water to bend.
If the vector lines created between the two Gaussian surfaces are curved, all the matter will follow these field lines as well. In this demonstration, instead of using a flat plane, I use two circular objects as my Gaussian surfaces. You can see that as the water settles after being sloshed around by me turning the wheel
on the Van de Graaff generator, it comes to rest with a curve in the surface following the electric field lines between the two spheres. This is why the ionosphere, a phenomenon that has never been created in a lab, is a theory yet to be verified, but is needed to create this phenomenon here on Earth. Maxwell himself changed Ampere's law, which stated plainly that without matter, no electrostatic
field can exist. Maxwell changed it with no scientific evidence, allowing it to gather magically above our heads in free space. Density and electric potential go hand in hand. The denser something is, the more electric potential it can hold.
Not that I believe in the model of the atom, but even the periodic table has a distinction on the amount of electric potential there is in the different elements. In this demonstration, I have a metal button hanging from helium balloons that keep the button buoyant just above the ground. By only adding more electrostatic potential to the button, you can see it will appear heavier
and force the buoyant object down along the vector lines created by the electrostatic potential difference. Without changing the density of the medium or the object, one can change the overall weight or gravitas of the object.
