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).
