Fig. 479. Fig. 478. force are shown for the case of both currents flowing away fromthe reader. Evidently the maximum number of lines of force foreach circuit exists when A and B are close together. Hence weshould expect attraction from Maxwells rule. The repulsion be-tween oppositely directed… … Ampere extended the above lawas follows: Two straight conductorswhich cross each other obliquely,attract each other when their cur-rents both flow towards or bothaway from the point of crossing;when one current flows away andthe other towards the crossing point,they repel each other. 705.
