These 20mm (0.79") wide square neodymium magnets are available in thicknesses of 5mm (0.2") or 10mm (0.39"). These high-performance, compact magnets are surprisingly strong for their size. The thickest of the magnets below produces an impressive pull of 14.2kg (31.31lbs) when in direct contact with a steel surface of equal thickness. They are great for experiments and engineering projects.
