These neodymium magnets are plated with 3 layers of protective coatings - Nickel + Copper + 18K Gold,
these magnets will have approximately 2, 800 Gauss on each face.
Neodymium Magnets are usually plated with 3 layers of protective plating. First a layer of Nickel, then a layer of Copper and then a final layer of Nickel. This plating can wear away in the course of normal use if it is sliding or impacting onto a steel surface. If the plating layers are worn away, then the magnet will be exposed to corrosion and since the magnets contain a high percentage of iron, they will rust easily. It is always better to use the magnet in a way that mechanically prevents it from ever touching the part that it is attracting. A mechanical stop which holds the magnet 0.2mm away from the attracted part will ensure a very long life of the magnet.
Neodymium magnets can be secured in place with adhesive or in some cases, with countersunk screws.
Magnets are sintered and extremely hard and brittle. You should never attempt to cut or drill into a magnet unless using diamond tooling and coolant (as the dust from cutting is very flammable).
Millions of people worldwide wear Neodymium magnets to promote health and well being. We have found no evidence at all of detrimental effects of Neodymium magnets on people or animals - quite the reverse!
