What are the advantages and disadvantages of plastic encased magnets?
The biggest drawback to Neodymium magnets is while magnetically very strong, they are very physically fragile. Tough coatings, such as nickel, go a long way toward protecting the magnets from cracks and breakage. However, after repeated impacts with each other or other surfaces, even the best metal coatings will fail. Plastic coatings offer an impact and corrosion protection for the fragile magnets inside. These magnets can sustain far more punishment than the standard metal coated magnets, making these a good play or experimention magnet. However, on the negative side, this relatively thick coating reduces the effective power of the magnet due to the logarithmic drop in magnet strength as the distance increases from the surface of magnet.
