260 PECULIARITIES IN THE MAGNETISM, &c. 
110. These two experiments were the only 
ones made in this inquiry ; for, as they had pro- 
duced the results I had expected, and thus verified 
the theoretical views I had entertained, it was 
easy to predict that any bar magnet, of sufficient 
length, might be made to display as many distinct 
and perfect magnets as we please, by the influ- 
ence of heat alone, when applied in a similar 
manner. 
111. The difference in the mechanical, and the 
calorific modes of subdividing a magnet into 
several smaller ones, consists in the subdivision 
of the metal in the former case, and the subdivision 
of the magnet only, in the latter. By the former 
process, however, the new poles are permanently 
fixed in the steel; whereas by the latter, they 
are transiently displayed, and change their situa- 
tion as the metal cools. Eventually the heated 
parts, after cooling, assume a diffused polarity.
