other. The entire magnet can be tilted over and employed, in conjunction with the levelling screws 

 supplied, with lines of force running perpendicularly. 



The stage fixed between the magnet limbs is rotary, can be adjusted in the plane and can also 

 IK- screwed in laterally in the baseplate. 2 iron cores are inserted above in the magnet limbs and can 

 removed for optical experiments. 



The winding is arranged for 20 amperes, consists of 2500 turns, and when in series has a resistance 

 of approx. 3.3 ohms and is intended for connecting up to 65 volts. 



With the . (inical pole pieces the pole distance is about 1 mm (30 sq. mm cross section) and 

 with -lo.uiMi ampere-turns the field is approx. 38,0(Hi gaii**.
