PM1055 Permanent magnets
A reference magnetA magnet used for calibrating a magnetometer. Reference magnets are often controlled or even regulated by an NMR teslameter. More in the palm of your hand
Metrolab’s permanent dipole magnets are serious scientific instruments, in a deceptively small and elegant package. Available in fields from 0.01 to 0.5 T, they are remarkably compact, weighing just around a kg and measuring 80 mm in diameter and 39 mm (0.01 – 0.27 T) or 55 mm (0.5 T) high.

NMR stabilization
All permanent magnets are sensitive to temperature. The strength of the core material itself decreases with increasing temperature, and thermal expansion changes the polePart of a magnet used to focus the flux in a gap.
