Frequently Asked Questions (FAQ)
What is the maximum weight this magnet can hold?
Its pulling force depends on the contact surface (e.g., sheet metal thickness), but generally, a 20x3mm N35 magnet can safely hold several kilograms under ideal conditions (vertical pull on clean, flat steel).
Are these magnets suitable for outdoor use?
Neodymium magnets are susceptible to moisture. Although they have a protective coating, for long-term outdoor use, additional insulation or choosing ferrite magnets is highly recommended.
