A reference magnet in the palm of your hand. Metrolab’s permanent dipole magnets are serious scientific instruments, packaged remarkably small and elegant. Available in fields ranging from 0.01 to 0.5 T, they are remarkably compact, weighing just one kilogram and measuring 80 mm in diameter and 39 mm (0.01 – 0.27 T) or 55 mm (0.5 T) in height.
