根据毕奥-萨伐尔定律推导了运动电荷产生的磁感应强度的公式，用曲面显示运动电荷产生的磁感应强度的分布规律。 通电线段的磁感应强度公式 磁感应线的半径形成等比数列，精确显示了二维磁感应线(Derivation based on the Biot- Savart law of magnetic induction generated by the moving charge formula, the distribution of magnetic induction surface display generated by the moving charge.)

This is a very useful code to detect copy moveimage forgery. Its input is any forged image and its output is the copied or pasted part only, by cropping the same the image.
