The 20mm x 5mm neodymium disc magnet has a pull force over 17 pounds (~8kg) and provides enough resistance to be used in eddy current (Hall effect) brakes.
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.
Read the complete Google Customer Review for: "...(Indigo) N42 Neodymium magnets...the real deal…bought magnets on Amazon advertised as N52… another cheap Chinese fake"
We also provide complete Documentation including MSDS & ROHS; see below.
The Mark I Magnaprobe can respond to as little as 0.3 gauss & will detect weaknesses in magnetic shielding. The Mark II Magnaprobe is a fast & convenient way to confirm magnet are positioned with their poles pointing correctly.
