. 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, iffree to… … Fig 104. Fig. 105. 97. Dielectric hysteresis.—The most prominent kind of di-electric hysteresis is a kind which is closely analogous to what istechnically called elastic lag in mechanics. For example, glasswhen subjected to a mechanical stress takes on a certain amountof strain (deformation)…
