This is a very strong and sturdy neodymium disc magnet. With N52 strength, these magnets should not be taken lightly. They must be handled with care because they can quite easily give a nasty pinch if you get between two of them. They are triple plated in black nickel which gives the discs an attractive, shiny black appearance. The DX04B is one of our best magician's magnets because of its compact size and high strength-to-size ratio.

This size is also available in grade N42 with standard Nickel plating as part number DX04.

Note: Our "Black Nickel" plating is achieved by adding a special tint during the nickel plating process. The resulting color is not black. The appearance of these magnets is best described as grey, charcoal or gunmetal. Due to this unique process, slight variation in color may occur from order to order.
