ination of magnetic uniformity along the length of a straight bar sanford] Magnetic Uniformity 5 emf is constant for a uniform bar and variations indicate non-uniformities. It is possible with suitable apparatus to obtain aphotographic record showing the degree of uniformity along thelength of a… … FlG. 4.—Form of the uniformity curve taken at different values of induction uniformity curve near the ends (Fig. 4). This effect is probablydue to the high magnetizing force necessary to produce highinductions. Readings taken at low inductions may be affectedby the previous magnetic history of the…
