s of the magnet, but ina more complete form of the apparatus the position of E canbe adjusted to secure this. By varying the position of E, thedirection of the force can be varied. Prof. Ayrton has devisedseveral pieces of apparatus for readily doing this; one simpleplan due to him is shewn in Fig.… … Fig. 103, Let the weight TTbe 500 grams, and place TOO grams inthe scale-pan. Adjust the pulley until the string AE ishorizontal. This can be secured by observing when it isparallel to a horizontal line marked on the apparatus, andwhen this is the case observe the angle of deflexion <^, bymeans…
