Neodymium super magnets: The strongest in the world
You might ask yourself: What makes a neodymium magnet a super magnet? And: Isn't a cheaper ferrite magnet sufficient for my project?
The special combination NdFeB leads to a high adhesive force even in small magnets. Hence, ferrite magnets of the same dimensions are much weaker.
We recommend super magnets if you need a small and light product that is also aesthetically pleasing with its even silver surface. The rare metal makes it a little bit more expensive though.
