Product Description
N42SH Neodymium Arc Magnet – High-Temperature Industrial Grade (ID-North Pole)
Designed for high-performance rotating machinery, this N42SH Neodymium Arc Magnet offers a perfect balance of magnetic strength and thermal stability. Measuring 3" OD x 2.5" ID x 0.75", these 90-degree segments are engineered from Grade N42SH rare earth material, which is specifically formulated to resist demagnetization in high-heat environments up to 150°C (302°F).
This specific model features an Inner Diameter North (ID-N) pole orientation, making it a critical component for building complex magnetic rotors, stators, and sensor arrays. When four of these segments are combined, they create a complete 360-degree high-energy magnetic ring.
