could maintain full fieldexcitation for nearly 4 seconds. It is interesting to note that the duration of the field dischargedoes not depend on the voltage, current, or size of the machine,but merely on, first, the magnetic flux and m.m.f., — whichdetermine the stored magnetic energy, — and, second,… … Fig. 12. — Magnetic Single-energy Transient. coil is not short-circuited upon itself, but its circuit closed by aresistance r. Such would, for instance, be the case in Fig. 12,when opening the switch S. ^6 ELECTRIC DISCHARGES, WAVES AND IMPULSES, The transients of magnetic flux, current, and…
