Fig. 1019 which it occupies (fig. 1019). Its magnetic susceptibility (722) is positive, andits magnetic permeability greater than unity. If, however, the substance ofthe sphere is diamagnetic—for instance, a ball of bismuth—the lines of forcein the field are apparently repelled, so that fewer lines… … susceptibility is negative and its permeability less than unity. A rod of ironplaces itself axially in a magnetic field, because in that position the numberof lines of force or induction passing through it is a maximum ; a rod ofbismuth similarly places itself equatorially to render the number of…
