emagnetic properties of iron and steel can be very closelyimitated. 88] EXPERIMENTS WITH MAGNETS 133 Thus suppose that by means of some impressed mag-netic force the old grouping is broken up and a new oneestablished; if this new grouping be very stable it willcontinue when the magnetic force is… … Fig. 861. as to produce no external field, the assemblage is like a pieceof soft iron. All these changes can go on under the mutualmagnetic forces between the molecules ; the assumption of aforce arising from friction or some similar action tending tohold them in their positions is not needed.
