N55 (FIFTY FIVE) NEODYMIUM MAGNETS

N55 NEODYMIUM MAGNETS – The strength of neodymium magnets increases as the grade number gets higher. N35 is the most usual grade for all applications, N55 is the highest but this is not yet widely available. We stock a range of N52 neodymium which is the highest grade that is currently widely and reliably available and these are the first of the N55 grade magnets that we have been able to secure.

N55 is the highest grade of neodymium magnets available. Be warned! They are strong and they will take you by surprise.
N55 is approximately 5-6% stronger than N52 magnets the same size.
These are ideal for magnetising larger wargaming models and for a range of science and crafting applications.

N55 magnets are the strongest magnets available nowadays for commercial use. Neodymium rare earth magnets strength is measured on a scale of 24MGOe-55MGOe. These powerful magnets were developed quite recently. This new grade of neodymium magnets is 5-6 percent stronger in compare with the more common N52 grade.
