The Influence of Magnets upon Each Other
Magnets and Currents:
If while our suspended magnetic needle is at rest in its characteristic north-and-south direction another magnet is brought near, the suspended magnet is turned; that is, motion is produced. If the north pole of the free magnet is brought toward the south pole of the suspended magnet, the latter moves in such a way that the two poles N and S are as close together as possible. If the north pole of the free magnet is brought toward the north pole of the suspended magnet, the latter moves in such a way that the two poles N and N are as far apart as possible. In every case that can be tested, it is found that a north pole repels a north pole, and a south pole repels a south pole; but that a north and a south pole always attract each other.
The main facts relative to magnets may be summed up as follows: -
a. A magnet points nearly north and south if it is allowed to swing freely.
b. A magnet contains two unlike poles, one of which persistently points north, and the other of which as persistently points south, if allowed to swing freely.
c. Poles of the same name repel each other; poles of unlike name attract each other.
d. A magnet possesses the power of attracting certain substances, like iron, and this power of attraction is not limited to the magnet itself but extends into the region around the magnet.
