How Are Magnets Rated For Strength?

How are magnets rated for strength? The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets 'strength'. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.

Which is stronger N35 or N52 magnet?

NIB magnets come in different grades, which correspond to the strength of their magnetic fields, ranging from N35 (weakest and least expensive) to N52 (strongest, most expensive and more brittle). An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49).

How strong is a N35 magnet?

What does N52 magnet mean?

N52 is shorthand for a neodymium magnet grade with an energy product or BHMax of 52MGOe (MGOe stands for Mega-Gauss Oersteds). N52 neodymium magnets are made from one of the most expensive grades and in some instances, a lower grade of neodymium will offer adequate performance at a significantly lower price.
