4 Neodymium Magnets 3/4 x 1/8" Disc PLASTIC COATED N48
ONE lot of 4 Magnets. Size: 3/4 inch diameter x 1/8 inch thick discs - which are surrounded by hard plastic shells for MAXIMUM DURABILITY. - Extremely powerful magnetic material. These discs are axially magnetized, so the strong North/South poles are in the center of the flat sides. That makes them easier to stack into a cylinder than to connect side by side.
