Neodymium magnets explained: what they are, grades N35–N52, coatings, shapes, and applications — plus how to source stocked or custom NdFeB magnets.

Axial, diametric, true radial and segmented ring magnets produce different fields and different manufacturing constraints. How each is made, where each fits, and what to put on the drawing.

What the letter after a neodymium grade actually means, how the N/M/H/SH/UH/EH/AH classes are defined, and how to pick one from your real operating temperature, magnet geometry and opposing field.
Shop and compare 10mm neodymium magnets, including 10mm diameter disks, a 10mm OD ring, and blocks or rods with a 10mm dimension. See sizes, pull-force context and stock sourcing options.
Epoxy-coated neodymium magnets use a black or application-specific protective barrier to improve corrosion resistance in humid, outdoor and moisture-prone environments. Compare epoxy vs. Ni-Cu-Ni plating, learn why epoxy is not automatically waterproof, see stocked epoxy-coated magnets, and specify coating thickness, temperature, corrosion testing and OEM documentation for custom NdFeB parts.

Practical guide to reading Br, Hcb/Hcj, BHmax, demagnetization curves, temperature coefficients, tolerances, pull force and minimum-versus-typical values.
