hether the core is large or small,and therefore the pull at this pointin the stroke is less when the area islarger. It is well to remember thatthe final pull of a magnet can be in-creased by making the area of contactsmaller. The net result of the en-larged core is to increase the startingpull and… … Fig. 22. Clapper TypeElectromagnet Portative, or Holding, Magnets Characteristics. The problem of designing a portative, orhoi ing, magnet is quite different from that of designing a tractivemagnet. With the tractive magnet the main thing is to get asmuch work out of it as possible and the final,…
