Product Overview
Neodymium bar magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N42SH high-temperature neodymium bar magnets manufactured to stringent quality standards using advanced production technology. These magnets provide reliable magnetic performance while maintaining strength in elevated-temperature environments.
This N42SH neodymium bar magnet measures 2" x 1/2" x 1/8" and generates approximately 13 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N40, N38, and N35 grades while offering superior temperature resistance.
Designed specifically for high-temperature applications, N42SH magnets can operate continuously up to 300°F (150°C). They provide significantly greater magnetic strength and often lower cost than alternative high-temperature magnetic materials such as samarium cobalt (SmCo), Alnico, and ceramic magnets.
What Is a High Temperature Neodymium Bar Magnet?
A high-temperature neodymium bar magnet is a rare earth permanent magnet made from neodymium, iron, and boron (NdFeB) that is engineered to maintain magnetic performance at elevated temperatures. N42SH magnets combine strong magnetic force with enhanced thermal stability, making them ideal for industrial, engineering, automation, and scientific applications.
How Strong Is This Magnet?
This N42SH neodymium bar magnet generates approximately 13 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 13,200 Gauss, it delivers powerful magnetic performance even in elevated-temperature environments.

Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides approximately 13 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, steel thickness, and application design.
What temperature can this magnet handle?
This N42SH 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.
Is N42SH stronger than N35?
Yes. N42SH provides significantly greater magnetic energy and holding force than N35 magnets while maintaining performance at higher temperatures.
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 1/8-inch thickness, with the north and south poles located on the 2" x 1/2" long surfaces.
