Product Overview
Neodymium block magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N50SH high-temperature neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength while maintaining reliable performance in elevated-temperature environments.
This N50SH neodymium block magnet measures 1.5" x 3/4" x 1/4" and generates approximately 30 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N48, N45, N42, N40, N38, and N35 grades.
Designed specifically for high-temperature applications, this magnet can operate continuously up to 300°F (150°C). It is significantly stronger and often more cost-effective than alternative high-temperature magnetic materials such as samarium cobalt (SmCo), Alnico, and ceramic magnets.
What Is a High Temperature Neodymium Block Magnet?
A high-temperature neodymium block magnet is a rare earth permanent magnet made from neodymium, iron, and boron (NdFeB) that is engineered to maintain magnetic performance at elevated temperatures. N50SH magnets combine powerful magnetic strength with enhanced thermal stability, making them ideal for industrial, engineering, automation, and scientific applications.
How Strong Is This Magnet?
This N50SH neodymium block magnet generates approximately 30 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 14,500 Gauss, it delivers outstanding magnetic performance while maintaining stability in elevated-temperature environments.

Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides approximately 30 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, alignment, and application design.
Is N50SH stronger than N42?
Yes. N50SH provides significantly greater magnetic energy and holding force than N42 magnets while also offering high-temperature resistance.
What temperature can this magnet handle?
This magnet is rated for continuous operation up to 300°F (150°C), making it suitable for elevated-temperature environments where standard neodymium magnets may lose strength.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides 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 1.5" x 3/4" faces.
