the magnet is very strong. this supplier has really good magnets. the ONLY thing that I don’t like is the plastic case on it. the case instantly broke when the magnet go to close to something that was metal by accident, and the magnet is so strong that it sucked onto it and the casing broke. other then the plastic case, which really isn’t a big deal, the magnet is incredible. I plan on ordering more stuff from this supplier.
