NIB magnets are significantly more powerful than your average refrigerator magnet. In fact, these powerful magnets are so intense that you may have to take precautions around them that are atypical. For instance, if you keep rare earth magnets in the home, you will want to make sure that they are at least a foot away from your computer, or your credit cards.

NIB is an acronym which stands for Neodymium Iron Boron, the metals which form NIB magnets. NIBs are a form or rare earth magnets, so named because of their place on the periodic table. Other rare earth magnets are made of samarium, which is also located in the periodic table's Lanthanide series.

The Strength of NIB Magnets

NIB magnets are particularly fascinating because of their great strength. If you experiment with NIBs that are grade N40 or higher, you'll notice that they can act on one another from as much as 12 inches away! These magnets are so strong that, if you have a pacemaker, you should talk to your doctor before experimenting with them.

NIBs can sometimes chip one another, if you allow them to repeatedly pull toward each other from a maximum distance. These magnets are usually nickel plated. You can only let them strike each other with full impact a limited number of times before they are apt to chip. These magnets are so strong that children should play with them only under adult supervision.
