Frequently asked questions
How should I handle this magnet?
The listing says the magnet is fragile and should be stored dry at room temperature. Keep it away from magnetic storage media and sensitive electronics such as compasses, and be careful of pinching fingers when two magnets snap together.
Can it be used above 80 °C?
No. The listing gives 80 °C as the maximum working temperature, so avoid heating it beyond that.
