20x10x5mm Block Magnets
SKU: 44251-5
Our 20x10x5mm magnet is compact but is surprisingly strong for its size.
Our 20x10x5mm magnet is compact but is surprisingly strong for its size.
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.
