bourhood are no longer uniformlydistributed. They crowd into the iron at one side and leaveit again at the other as shewn in Fig. 76a; the iron is said tohave a greater permeability to the magnetic induction thanthe air which it displaces. If the sphere be diamagnetic the distribution of the… … Fig. 77. thick shell of iron acts as a magnetic shield, the lines of forcefrom outside do not enter the air space in the interior of theshell; the magnetic force within is much less than it wouldbe if the ring were removed.
