Neodymium magnet shapes
Disc and cylinder magnets
Disc and cylindrical shapes cannot be identified as NdFeB by appearance alone. Documentation, dimensions, how consistently the lot is sorted and origin are relevant to the initial assessment.
Four key details
Information needed for assessment
- 01Diameter and height
- 02Markings or material data
- 03Single-type or mixed lot
- 04Attached materials and foreign parts
Material identification requires evidence
Magnetic force, colour, coating or geometry alone are insufficient. Documentation, origin and, where appropriate, suitable analysis determine the material classification.
