Circular disc magnets range from 0.5mm to 65mm thick which makes them suitable for almost any magnetic application.
Circular disc magnets can be fixed in place using adhesive or can be pushed into circular drilled holes 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!
Ferrite (ceramic) disc magnets while not as strong as neodymium magnets offer excellent value for money when strength is not the most important factor.
