on neodymium magnets:

The magnets listed below are very powerful, much more powerful than magnets most people have seen, and need to be handled with proper care. The magnetic fields from these magnets can affect each other from more than 12 inches away. Please note that these magnets are fragile. Even though they are coated with a tough protective nickel plating, do not allow them to snap together with their full force or they may chip, break, and possibly send small pieces of metal flying on impact. Our larger magnets can easily bruise fingers and even break finger bones as they attempt to connect together. Always wear protective eyewear or safety goggles when handling the magnets. Keep magnets away from any magnetic based storage devices such as desktop or laptop computers, hard drives, floppy disks, cassette tapes, VHS tapes, or credit cards. A distance of at least 12″ should be kept between magnets and these items at all times. Keep them away from computer monitors, VCR’S and TV’s, non-electronic wrist watches etc. If you or someone in your household has a PACEMAKER or another electronic surgical implant, don’t even think of ordering these items. Neodymium magnets are not suitable for children to play with, and should only be handled under strict adult supervision.
These Neodymium magnets are made to very demanding standards, however uses should be restricted to operating temperatures below 180° Fahrenheit (80° Celsius) or they will lose their magnetic properties.
