About Neodymium Magnets

Yes, if moisture reaches the iron-rich alloy. The plating prevents it in dry conditions; coated magnets protect better.

Neodymium magnets are much stronger for their size. Ceramic (ferrite) magnets cost less, resist corrosion and handle more heat.

Magnetic badge holders attach without pins or clips, so they don't damage clothing and move easily between outfits.

Neodymium magnets are available in a wide variety of grades such as N42, N52 and N42SH. The grade is a good indicator of the strength of a magnet. In general, higher numbers correlate with a stronger magnet. It all starts with the letter "N", representing neodymium. The following number comes from an actual material property, the Maximum Energy Product of the magnet material, expressed in MGOe (Mega Gauss Oersteds). It represents the strongest point on the magnet’s Demagnetization Curve, or BH Curve.  Simply put, the higher the grade, the greater the magnetic field that magnet will generate which equates to more strength.   High Temperature GradesNeodymium magnets have what is generally considered...
