ayers, the inside layer having large inductivity, the middle layerhaving medium inductivity, and the outer layer having smallinductivity. Such a cable insulation is called a graded cableinsulation. 96. Magnetic and electric parallels,is analogous to electric inductivity. Magnetic permeability The… … Fig. 102. Fig. 103. ELECTRIC FIELD. 159 The iron rod in Fig. 102, iffree to turn, oscillates back andforth through an equilibriumposition parallel to the field. An iron plate is drawn intothe intense magnetic field be-tween two opposite magnetpoles as shown in Fig. 104. The glass rod in Fig. 103,…
