Will the Powerful Neodymium Magnet rust?
Any material containing iron will rust, unless properly protected. Information on our Rare Earth and Ferrite magnets are as follows:
RARE EARTH
Our Rare Earth magnets are spray-coated in a protective nickel coating to combat corrosion. This coating is susceptible to chipping, which may allow corrosion to occur.
FERRITE
Our Ferrite magnets are un-coated, but are less susceptible to corrosion due to their consitution. They are ceramic in nature which gives them a greater resistance to rust, however over time may require some form of coating or protection.
How can I prevent rusting?
Rusting occurs when iron is exposed to air and moisture. The way to combat rusting is to prevent exposure to air and moisture.
This can be done by coating/sealing the magnet or metal entirely in some protective layering (such as plastic, rubber, glue, etc.).
Make sure you have sealed the magnet surface entirely! You need to cut off all sources of oxygen and moisture.
Will a protective coating affect the Powerful Neodymium Magnet?
Magnets operate when brought into proximity with iron.
When you apply a coating, you increase the distance between magnet and iron.
Therefore, thick coatings will result in a reduction in magnet strength.
