Frequently Asked Questions (FAQs)

1. Can neodymium magnets be turned off?

Generally, no. The neodymium magnets we provide are also called, “permanent magnets.” The word “permanent” means they stay magnetized for a long time. They are always on. This is the opposite of an electromagnet, where you have to run an electric current through a wire whenever you want it to act like a magnet.

2. Can you demagnetize a rare earth magnet?

You can demagnetize them by heating them to the Curie temperature, but that may be inconveniently high, e.g. 350°C. Another option is to heat to some lower temperature and apply a smaller ac field than would be needed at room temperature.

3. Are rare-earth magnets harmful?

If multiple rare-earth magnets — each the size of a BB pellet — are swallowed, they can pull together inside the intestines, potentially causing life-threatening holes and blockages. Emergency surgery is the usual result.

4. Does stacking rare-earth magnets make them stronger?

Stacking multiple magnets together can make them stronger. Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size.
