The magnet is surrounded by six equal square faces, and the
angle between any two adjacent faces of the magnet is a
right angle.
This magnet is made of neodymium and is 21 times stronger
than a ceramic magnet of the same size.
They are magnetized by thickness. They are composed of
neodymium iron boron magnetic material, and are plated with
nickel, copper and nickel, and have a shiny,
corrosion-resistant surface.
