Frequently Asked Questions
How much weight can this magnet hold?
This magnet provides more than 1,300 lbs of pull force under ideal laboratory conditions. Actual holding capacity depends on steel thickness, surface condition, alignment, air gaps, and installation method.
Is N42 stronger than N35?
Yes. N42 provides significantly greater magnetic energy and holding force than N35 magnets of the same size.
What direction is it magnetized?
The magnet is magnetized through the 2-inch thickness, with the north and south poles located on the 6" × 4" faces.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance. For long-term outdoor or marine use, additional sealing or a protective enclosure is recommended.
What is the maximum operating temperature?
This standard N42 magnet is designed for continuous operation up to 176°F (80°C). Exposure to temperatures above this limit may permanently reduce magnetic strength.
