Where are the poles?

For rectangle/bar magnets... All our rectangular magnets are magnetized through the thickness.. The poles are always on the surfaces of the 1st two numbers of the measurements.

On round magnets... The poles are always axially magnetized through the thickness...This means the poles are on the flat surfaces unless stated that they are diametrically magnetized which means the poles will be on the curved sides.

Coating

Support all magnet plating , like Ni, Zn, Epoxy , Gold, Silver etc.

The Gauss Ratings

The amount of magnetism [brmax at the center] of a magnet is measured in Gauss. This is a measure of the penetration of a magnet. Below is a table of the Gauss ratings of the most popular neodymium magnets:
Grade Gauss
N35 11,700-12,100
N38 12,100-12,500
N40 12,600-12,900
N42 12,900-13,200
N45 13,500-13,800
N48 14,000-14,200
N50 14,300-14,500
N52 14,600-14,800
