(16128a) k1vB (16128b) K is known as the mmf drop per unit length, the eld gradient, or the eld intensity It is a vector whose magnitude is proportional to that of B and whose direction is along B Both B and K are quantities de ned at every point of a magnetic eld Hence Eq (16128b) expresses a point relation and holds true at every point of a eld, irrespective of whether the eld is uniform or not 39 Units The relations developed above are general and hold true independently of the units used For purposes of numerical computations, however, it is necessary to use a consistent set of units, as listed in Table 165 With this choice of units, the constants k1, , and v in Sec 37a, for air or vacuum, become k1 1 (4 )10 3195 1257 10 henry per cm3

(16130) The relations in Eqs (16130b) and (16130b ) are point relations and hold true irrespective of whether the eld is uniform or not The remaining equations in Eqs (16130) apply only to a uniform air eld wherein l is the length of the ux path and A is the crosssectional area perpendicular to the direction of ux 40 Series and Parallel Reluctances and Permeances Two permeances are in parallel if the same mmf acts on them Two reluctances are in series if the same ux path passes through them Expressions for the equivalent permeance of a parallel circuit and the equivalent reluctance of a series circuit are developed as follows Equivalent Permeance Consider a set of n permeances in parallel Let the ux through each of them be

41 Magnetic Properties of Matter According to its magnetic properties, matter falls into either one of the following classes: 1 Diamagnetic matter 2 Paramagnetic matter a Ferromagnetic b Nonferromagnetic Diamagnetic matter includes substances whose magnetic permeability is less than 0 Among these may be mentioned antimony and bismuth The permeability of bismuth, which is one of the most highly diamagnetic substances known, is 1254 10 8 H / cm3, which is not very different from 0 1257 10 8 Paramagnetic matter includes substances whose magnetic permeability is equal to or greater than 0 Air, wood, copper, brass, etc have a permeability which is approximately 0 Iron and iron alloys and nickel and cobalt and their alloys have permeabilities varying from 0 to 105 0, depending on the ux density used and the composition of the alloy This latter class of paramagnetic matter which possesses high permeability is referred to as ferromagnetic in order to distinguish it from nonferromagnetic matter, whose permeability is very close to that of vacuum The absence of materials of very high reluctivity accounts for the fact that there is no known magnetic insulator Such an insulator, if it existed, would have a very low permeability or very high reluctivity The reluctance of a path made of this R would be low In material would be high, and hence in the relation M order to appreciate this fact, compare the ratio of the resistivity of insulators to that of conductors with the ratio of the reluctivity of paramagnetic or diamagnetic materials to that of ferromagnetic materials as follows: Resistivity of silver: 1 163 10 6 Resistivity of guttapercha: 2 37 1014 Reluctivity of permalloy: v1 2 10 5 Reluctivity of bismuth: v2 8 107 37 163 8 2 1014 10 6 107 10 5 4 227 1012
