near the other end of the iron ; the iron is attracted. 

 Eepeat the experiments with the other end of the magnet ; 

 in each case the iron is attracted. From these experiments 

 we have a right to conclude that either pole of a magnet 

 will attract ordinary iron.

 Freely suspend three bar magnets, A, B and (7, at some

distance from each other. (Place each magnet in a stout 

 paper stirrup supported by a cord ; or place each upon a 

 board or cork floating on water.) When- they have come to 

 rest, each will lie in a north and south line. Magnets are 

 chiefly characterized by the property of attracting iron and 

 this tendency to assume a particular direction of position 

 when freely suspended. Mark the north end of each sus- 

 pended magnet , and the south end of each, +. ( 317.)
