r-acteristics of the other types. If theplunger of the magnet in Fig. 11 beplaced partly inside the coil and thecoil energized, the plunger will of coursebe magnetized; mutual attraction willthen take place and the plunger willbe drawn into the coil. If the plungeris the same length as the coil, it… … Fig. 11. Solenoid and Plunger 262 ELECTROMAGNETS AND COILS 23 A characteristic pull curve of a solenoid-and-plunger magnetin which the coil and the plunger are of equal length is shown inFig. 12. It will be noted that when the plunger is withdrawnuntil the bottom of the solenoid is even with the…
