IHK INDUCTION FACTOR 



two adjacent conductors is centimetres, and the cylin- 



o ./ 



driral area enclosed by them is " square centimetres. If 



A 



dn lines enter the cylindrical surface between them, - 

 will be the intensity of magnetisation at the surface of the

cylinder, that is, the number of lines per square centimetre 

 crossing the tangent plane to the cylinder at that point. 



In Fig. 3, d represents the axis of one of the conductors 

 lying in the cylindrical surface, and we assume that the 

 lin.'- of force enter the cylinder in the direction indicated 

 by tin- sln-af of arrows, so that the plane at right angles 

 to the lines of force makes an angle of 6 degrees with (he 

 tanu'fnt plain- at '/, the line cdc representing a portion of the 

 cylindrical surface in a plain- at right angles to the shaft.
