WebOnce you move into extremely frigid conditions (below -135°C), the field will begin to diminish. With neodymium magnets, field strength will decrease by 85-90% at the boiling point of liquid nitrogen (‑196°C). This is caused by the molecules in the magnet falling out of the good alignment seen at lesser temperature drops. WebGenerally, they will show a reduced pull force, the extent of which depends on the size and shape of the magnet, and the environment in which they are applied. Through careful design, ferrite magnets can continue to function at temperatures …
