对动态电荷群的研究得知能够实现这种悬浮力。 较简单的情形是只要两个动态点电荷满足三个条件，它们各自受到的力就会指向同一方向，力的大小按正弦规律变化，合力不为零且稳定不变。
A simple type is that the forces on two dynamic point charges have the same direction, the scale of the forces are changeable with sine regularity and its' resultant force is stable and nonzero.
因为移动的电荷会产生电流，变化的磁通量会产生电压，新的设备会从电流中产生电压，像电阻一样，不过是以更加复杂、动态的方式。
Because moving charges make currents, and changing magnetic fluxes breed voltages, the new device would generate a voltage from a current rather like a resistor, but in a complex, dynamic way.
通过比较，动态法操作简单，结果精确度较高，成为测量基本电荷量比较实用的一种实验方法。
By comparison, it can be found that the dynamic method has simple operation and high precision, so it becomes one kind of practical methods in basic charge measurement.
