C>1'. L'74. Joule's Electromagnet, with broad, flat pole surfaces (Kolbe-Skellon, Introduction 

 to Electricity, Part II, Fig. 104 B), of horse-.shoe section, with suspension rings and 

 armature, Figure; carrying capacity when supplied with current by an accumulator 

 or a bichromate cell, about 120 and 70 kg respectively; own weight 1 kg 



!7. r >. Elektromagnet, Figure, with suspension ring and armature 



Tin- electromagnet carries 50 kg. 



!7(i. Electromagnet carrying 50 kg, in wood frame, F i g u r e, arranged to rotate about 

 the horizontal axis, with armature, balance pan and armature chain (Gan.-Kein. 

 Fig. 1(07) 



As the electromagnet run be removed from the fillet by loosening two screws it is possible to 

 u*e tin- magnet alone without frame. 



<>2,277. Electromagnet carrying 100 kg, F i g u r e, in wood frame, with limbs 250 mm long, 



armature and balance pan 



The armature is, as in the preceding item, fastened to a chain in accordance with Grimsehl's 



suggestion. 



<ii'.278. - - idem, arranged so as to rotate, F i g s. A and B, with wood frame stretched 



with cardboard, armature and balance pan 



In addition to being used in experiments on can vin raparity this Electromagnet can be employed 

 for other purposes, e. g., for demonstrating the lines of force by using the wood frame intended for 

 the purpose, cf. Fig. t>'2 '278 B.
