he magnetic moment equals the strength of thepositive charge into the distance between the two. Since this isso, it follows that all the theorems which were established inChapter V. in respect to electric force will be true also for polarfield. Thus, if a closed surface be drawn embracing the… … if the magnets lie entirely outside the surface. If, however, thesurface be drawn so as to enclose an unequal number of positiveand negative charges—for example, if in the case of the uniformlymagnetised filament (191, i.) it surrounds only one of its ends—thenthe total outward normal field is iir…
