These magnets might be small but they never fail to impress when their strength is on show. Each magnet goes through rigorous manufacturing procedures that are designed to prevent signs of corrosion. The Neodymium is coated in Nickel, Copper and Boron to enhance the lifespan of the magnet and the coating also gives off a smooth finish. These magnets are commonly used in industries like engineering, manufacturing and packaging for their strong magnetic properties. They are also often used in theatre design, model making, exhibition design and furniture making.
