Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating.

The most common type of plating for neodymium magnets, Nickel (Ni-Cu-Ni), is intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode outdoors in prolonged exposure to salt water, salty air, or harsh chemicals.

A Magnetic field is an invisible flux moving from one end of the magnet to the other. The flux consists of moving or spinning electrically charged particles invisible to the eye. If the max working temperature meets the requirement, permanent magnets can retain the magnetic field for a very long time, even forever.

Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
