is Magnetic pole identifier ( Magnetic pole searcher) ?
Identifier is a great tool for identifying the poles of magnets. A small magnet
is painted on both ends and is suspended, free to rotate, in a plastic housing.
The blue end of the magnet is the North pole and will point toward the South
pole of other magnets. The red end is the South pole and will point toward the
North end of another magnet.
This tool is
even more useful for showing the direction of magnetic field lines. Magnetic
field lines connect the North and South poles of a magnet. If moved around near
a magnet, the small magnet in the Pole Identifier will rotate and keep the
magnet aligned with the magnetic field line.
