Use our 20x10x5mm N42 grade neodymium block magnets for small-scale renewable energy experiments, or powering low-energy devices.

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

We also provide complete Documentation including MSDS & ROHS; see below.
