Frequently Asked Questions

How much weight can this magnet hold?

This magnet provides over 105 lbs of pull force under ideal conditions. Actual holding capacity depends on the steel surface, alignment, air gaps, and installation method.

Is N45 stronger than N42?

Yes. N45 magnets provide greater magnetic energy and holding force than N42 magnets of the same dimensions.

What direction is it magnetized?

The magnet is magnetized through the 1/2-inch thickness, with the north and south poles located on the 3" × 1" faces.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides excellent corrosion resistance. For prolonged outdoor or marine use, additional sealing or a protective enclosure is recommended.

What is the maximum operating temperature?

This standard N45 magnet is designed for continuous operation up to 176°F (80°C). Exposure to higher temperatures may permanently reduce magnetic strength.

Do you offer wholesale pricing?

Yes. Contact Super Magnet Store for competitive wholesale pricing and volume discounts on N45 neodymium block magnets.

Safety Notice

Neodymium magnets are extremely powerful and can snap together with significant force, causing pinch injuries or chipping. Keep away from children, pacemakers, sensitive electronics, and magnetic storage media. Always review magnet safety guidelines before handling or installation.
