N35 Magnets – The Ultimate Guide

Uncover every single fact about the N35 Magnets to facilitate the decision on the right magnet choice. Keep reading this comprehensive guide!

N35 Magnets Overview

The term N in N35 magnets reflects neodymium magnets. Among the series of neodymium magnets, N35 is the first one in the N-series. It is a permanent magnet. What adds up to the differentiation of this magnet from others is magnetic strength.

It is a stronger magnet than most samarium cobalt magnets, ferrite magnets and alnico magnet. The N series of neodymium magnets start from N35 and ends on N52. Therefore, in these grade series, the N35 magnet features the lowest magnetic force.
