This appears from examining Magnets of different 
Lengths. And this is the Reafon why in the fame 
Magnet the Curves are lefs in proportion to their 
greater Diftance from the Ends of the Bars. For 
the Poles from whence thefe Curves arife are pro- 
portionably nearer each other.

If the South Pole of one Magnet be oppofed to* 
the North of another, mod of the magnetic Matter 
is carried dire&ly out of one into the other: and 
does not return back in curve Lines till after having 
paired through both Magnets. It appears from the 
Arrangement of the Filings that the magnetic Mat- 
ter proceeding from the polar Surface does not now 
diverge from the Axis as before, but runs more in 
(freight Lines till it arrives at the polar Surface of 
the other Magnet,. The Curves arifing from the 
Sides, which before were bent towards the oppofite 
End of the fame Magnet, are many of them now 
bent the contrary Way towards the correfponding 
Sides of the other Magnet. Thofe which are not 
bent the contrary Way are fuch as are too remote 
from the oppofed Pole of the other Magnet to be 
influenced thereby s and therefore continue their na- 
tural Courfe,
