A selection of high-performance neodymium (N42) magnets measuring 13-14mm in diameter (for disc/sphere magnets) or 13-14mm wide/long (for rectangular magnets). Each magnet has an unbelievable performance for its size.
Small neodymium magnets can be fixed in place using adhesive or can be pushed into drilled holes or grooves in wood or plastic. Many new packaging designs use neodymium magnets cleverly trapped behind laminations of cardboard to provide invisible closing mechanisms for folders, gift boxes, name badges and even greetings cards that stick to your refrigerator!
Neodymium magnets attract each other with almost twice the force that they use to attract steel objects. They also attract each other through very large distances, even small magnets will attract each other through the thickness of your finger!
