Neo magnets are super strong and very useful all around the house, office, and workshop. Neodymium disc magnets are particularly sold for domestic use. Although they are small, these discs are still very hazardous and should be handled with care and kept out of reach of children.
Additionally, one should handle separate magnets with care as they can snap back and pinch the skin. A NdFeB disc is a permanent magnet that will retain its magnetism for several years. This is particularly if used in a favorable environment that cannot interfere with its plating or coating. They are made of neodymium, iron, and boron and this is the strongest manmade alloy. A neodymium disc magnet, as mentioned above, has many uses around the office, house, garage or workshop. Some of the uses are summarized as shown below.
- Door Catches. Small neodymium disc magnets are capable of pulling a twisted cabinet door straight. It can also hold it locked
- Use on fixtures, hardware, and jigs
- Hanging items. These magnets are so strong that they can even be used on a corner dry wall that has a metal core.
- Neo disc magnets can be used in wood and other surfaces as long as they are backed by steel.
- Holding tools on the edge of a workbench for easier retrieval
Neodymium disc magnets should be kept from electronic devices such as televisions, computer hard discs, Halbach Array, floppy discs, cassette tapes, bank cards, credit cards, and related items. This is because their strong magnetic fields can wipe out data on some of the electronic items mentioned above as they store it magnetically. Because drilling, screwing and machining these small items is a sensitive task, it should be done professionally. Neodymium is very breakable even though hard. So if machined with the wrong equipment it can break easily and become waste.
To attach these discs to a particular surface use special adhesives made for use with neodymium magnets. Epoxy glue could also be used. Finally, customers should pay attention to the sizes of NIB magnets. These will depend on the applications one has. One thing is for sure though, that a very tiny neo disc magnet will hold an item that is two or more times heavier. One will find that the full force of each magnet is indicated. For instance, neodymium disc magnets measuring ¼ x1/10 inches have a magnetic strength of 2.5 lb.
