Neodymium Magnets

By volume, a neodymium magnet stores about 18 times the magnetic energy of a ferrite magnet. How much it holds depends on its size, its grade and what it sticks to. Each product lists its pull force, and our MagNet pull force calculator shows what reduces it.

Choose neodymium when you need the most strength from a small magnet. Ferrite costs less and resists corrosion without a coating, so it suits larger, lower-cost parts: see our ferrite magnets. For heat, choose samarium cobalt or a high-temperature neodymium grade: see our high temperature magnets. Our magnetic materials guide compares them.

Each product title shows its grade as an N number. The number is the magnet’s maximum energy product: the higher it is, the stronger the magnet for its size. Letters after the number mean the magnet can work at higher temperatures. Our neodymium grades guide lists every grade, and each product page lists its maximum temperature.

Uncoated neodymium easily corrodes, so neodymium magnets are plated or coated to protect them. Coatings include nickel-copper-nickel, black nickel, zinc, gold, copper, titanium nitride, epoxy and PTFE (Teflon), and each one suits different conditions. Our coatings guide compares them.

They are safe with care, but they are strong. Two magnets, or a magnet and steel, can snap together hard enough to pinch skin or chip the magnet. Keep them away from children, pacemakers and other medical implants, and from electronics. Our magnet safety guide covers handling, storage and safe distances.
