Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 13.5 lbs of pull force under ideal conditions. Actual holding capacity depends on the surface material, air gap, and application design.

Is N42 stronger than N35?

Yes. N42 magnets provide substantially greater magnetic energy and holding force than N35 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides good corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually result in rust.

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 1" x 1/4" surfaces.
