armature-conductor in substantially equal 

 field densities at any instant during 

 movement into or out of the field. This 

 was not the case where no horns were 

 used, or where the field was abrupt and 

 permitted, say, one-half the section of 

 the armature- conductor to be at any in- 

 stant cutting dense lines, and the other 

 half to be moving in a field of little density. 

 Making the conductor of insulated strands, 

 and twisting the strands, was the remedy 

 indicated.
