 at n 2 to flow contrary to the direction of the hands of 

 a watch, hence n 2 is a north pole and s 2 a south pole, 

 and the two like poles, Si and s 2 > repel each other. 

 When the two electro- magnets are not both in the

 clined to each other at any angle, or are placed side by 

 side, it is no longer possible that the whole of the 

 currents of both magnets can be in the same or opposite 

 directions. In these cases the mutual behaviour of the 

 two magnets depends on the direction of those portions 

 of the currents in each magnet which are in close 

 vicinity to each other, because the action of currents
