求翻译：我们已经了解到，磁极之间的力，与它们之间距离的平方成反比，与它们单位面积的平方成正比。这与一个正负点电荷之间的相互作用力是相同的，也就是说它在物理特性上与电子完全相同。但是，电子本身只会带负电，运动的电子本身就会产生电流。可当我们直接接触磁场或让磁场穿透我们的身体时，我们没有任何不适的感觉。事实上，我们每天都生活在磁场中，也就是说电子本身不会直接参与这种作用力。是什么意思？

We have learned that the force between magnetic poles, and inversely proportional to the square of the distance between them, and they are proportional to the square unit area. This is a negative interaction between the point charge is the same, that it is exactly the same physical characteristics a

We have learned that the power poles, the distance between them with square, flat area is proportional to the square with them. This with a positive or negative interaction between the point charges are the same as the power, that is to say, it on the physical properties with electronic identical. H

We already understood, between the magnetic pole strength, the distance square is in reverse proportion with them between, is proportional with their unit area square.This and between a positive and negative point charge mutual action is same, in other words, it is completely same in the physical pr

We have learned that, between the poles of force, and inversely proportional to the square of the distance between them, and their unit is proportional to the square of the area. This is an interaction between a positive and negative charge are the same, which means it in exactly the same physical c

We have already known, the strength between the magnetic pole, is inversely proportional to the square of distance between them, proportional to the square of their unit area. This the same in mutual effort between some electric charge with one plus or minus, that is to say it is exactly the same as
