This is a pack of Hobbytech Neodymium N52 Magnets 3x1mm 50 pack.

Neodymium is the strongest rare earth magnet material, and N52 is among the highest grades of neodymium, making N52 magnets some of the strongest magnets on the planet.

Neodymium magnets are permanent magnets and lose a fraction of their performance after many years if maintained and used in ideal conditions.

The Hobbytech magnet range is marked on its "North Side" to ensure ease of use and polarity facing.
