磁性的起源

这是关于以下问题:“为什么运动电荷产生磁场?”已回答……但是我有一定的怀疑澄清。但是在那之前我要告诉你,对于大多数印度学生,静电学的基本是没有完成16岁甚至rativity甚至没有提到的12个标准(什么? ?-我知道!)…首先,在第二段为什么会有净当前.....左边(我应该先问什么是中性线)……,它是两种对立的线,由无限的指控吗?顺便说一句不反对指控消掉了,这样没有净电流引起据说对方负费用等于多少?最后,我一直都想问的问题是这样的。移动电荷产生的磁场吗?是的。 But is the underlying cause of the magnetic field, the electric field that changes to the moving charge? Or does it have anything to do at all with the electric field of the moving charge? Consider an isolated positive charge initially at origin. It sets up an electric field in the surrounding. Let's consider a point C on the surrounding such that the field is constant as long as the charge is stationary. Now say the charge is made to move with a constant velocity in the x direction.(by some external means such that the field is not disturbed by the external force). The electric field at C must change.. does this cause a magnetic field to be set up? AND I DON'T REALLY UNDERSTAND HOW TO FIND ANSWERS TI MY QUESTIONS... SHOULD I JUST TYPE MY QUESTION IN THE SEARCH BOX OR WHATT? HELP ME....

很难按照你的问题没有照片的细节,但我可以做一些有益的建议。

这是一本好书,了解电和磁e·珀塞尔。(我很幸运我根据那本书的作者在大学第一学期)。

你的直觉,它是字段之间变换电气(E)和磁(B)是完全正确的。如果你知道(E,B在一帧一个€喜爱)你知道它在所有其他帧利用相对论变换规则。我们讲述的故事线电流,床单,等都是非常有用的方式帮助我们理解规则,和珀塞尔pprovided这样的故事。
