Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides approximately 420 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, steel thickness, air gaps, and application design.
Is N42 stronger than N35?
Yes. N42 provides significantly greater magnetic strength and holding force than N35 magnets of the same dimensions.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but additional protection is recommended for prolonged outdoor or high-humidity environments.
Can it rust?
The protective nickel coating helps resist corrosion; however, damage to the coating or prolonged moisture exposure may eventually allow corrosion to develop.
What direction is it magnetized?
This magnet is magnetized through one axis of the cube, with the north and south poles located on opposite faces.
