Titanium tweezers can be used to handle small disc magnets & position them easily. 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.
