N52 Neodymium Disc Magnet 2-1/2"x1/2" Rare Earth Disc Magnet
These N52 Disc Magnets measure 2 1/2" in diameter and 1/2" thick and is made of a grade N52 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality systems.
Our small Neodymium Disc magnets are used both in the high tech arena and at the opposite end of the spectrum by individual hobbyists, inventors & tinkerers. These Disc magnets are neodymium strength grade 52. These Disc magnets are Coated in a Nickel, copper nickel layered plating for both protection of the magnet & it gives the magnet that nice shiny silver finish. N52. Neodymium is actually an alloy consisting of the Neodymium magnetic material, iron & boron. These Disc Magnets are typically used To help keep objects secured, for personal projects, crafts and closures, Hold things up, Hold things down, hold Curtains together or keep things fastened to any ferrous surface.

Together with an 8-pound bar of copper, I was able to beautifully demonstrate Lenz's Law in my physics classroom. My students loved spinning the magnet next to it and watching it defy gravity as it slowly slides down the side of the copper bar.
