The rectangular NdFeB 25x10x5mm flat bar magnet can hold over 12 pounds; strong enough to support heavy objects.

Some 3D printer applications have used this magnet in place of the 20X5X5mm Nd block magnet.

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.

Details

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.
