external magnetic.

conveyor magnets these magnets under the influence of the original magnet, neatly lined up, magnet tube so near the end of the magnet has a magnetic polarity opposite to and attract each other.Drawe magnets low temperature coefficient, the maximum operating temperature up to 350 ℃, negative temperature is not limited,Grate Magnets There are many iron having two opposite poles of the original magnet, in the absence of a magnetic field,Magnet Tube sthese original magnets disorganized, they cancel each other's magnetic, neodymium block magnets do not display the external magnetic.
