About this product
A round NdFeB (neodymium) permanent magnet measuring 17 mm x 15 mm, with a three-layer nickel-copper-nickel coating that protects the magnet from corrosion. It is magnetized through its thickness, with the N and S poles on the upper and lower faces, which suits holding, mounting, and sensing projects.

Frequently asked questions
Which faces are the poles?
The magnet is magnetized through its thickness, so the upper and lower flat faces are the two poles, one N and one S. Check the marking or test with a compass before mounting.
What is the nickel-copper-nickel coating for?
The three-layer coating protects the neodymium material from corrosion and surface damage. Neodymium magnets are brittle and rust easily without a coating.
