N50 Neodymium Cylinder Magnets 3/8 x 3/8 Inch (10mm x 10mm) – Strong Rare Earth Rod Magnets for 3D Printing, Woodworking, Cabinet Closures & DIY, 16 Pack

Drop one of these N50 cylinder magnets into a 10mm printed pocket mid-print and the lid snaps shut with no glue, no latch hardware, no visible fasteners. The same logic applies at the woodworking bench: bore a 3/8-inch Forstner hole, press the magnet flush, and a cabinet face, jig fence, or hidden drawer panel locks in place with up to 10.5 lbs of pull. That is the practical case for N50 over N35 — roughly 40% more energy product in the same footprint, which matters when working through wood or a printed wall.Each magnet is 10mm diameter by 10mm long (3/8 x 3/8 inch, 1cm x 1cm), axially magnetized, with triple-layer nickel-copper-nickel coating. The NiCuNi plating is smooth and hard — it will not flake onto a sanded surface or scratch a PLA enclosure. Maximum operating temperature: 80°C (176°F). Like all neodymium magnets, these are brittle — avoid letting them snap together at speed or drop onto concrete.The 10mm cylindrical form fits a standard 1/2-inch copper or aluminum tube — drop the cylinder through and watch it descend in slow motion as eddy currents oppose its fall, a vivid Lenz's Law demonstration that needs no additional equipment beyond the tube.Will it hold through a 3mm printed wall? Yes — pull force remains effective through typical FDM enclosure thicknesses. Seat without play in a 10mm Forstner hole? Yes — precision diameter gives a snug friction fit with no epoxy needed for most closures. Pack of 16: enough for a multi-door cabinet, a set of modular print enclosures, or a classroom demo kit.SAFETY: These magnets can pinch skin. If swallowed, multiple magnets attract through intestinal walls and cause serious injury — keep away from children. Keep away from pacemakers and electronics. Not suitable for children under 14.

• N50 HIGH-GRADE PULL FORCE: Each magnet delivers up to 10.5 lbs — stronger than standard N35 grade in this size — securing 3D-printed enclosures, wood closures, and workshop fixtures without extra glue
• PRECISION 10MM DIAMETER FOR EXACT FIT: The 3/8-inch (10mm) cylinder seats in a standard 10mm drilled hole or printed pocket with no filing — critical when tolerances decide whether a lid closes flush
• VERSATILE APPLICATIONS: Embed in 3D-printed lids and assemblies; press-fit into 3/8-inch Forstner-drilled wood for furniture closures, shop jigs, and hidden compartments; use as magnetic tool holders
• 16-PACK WITH NICKEL PLATING: Includes 16 axially magnetized cylinder magnets, 10mm x 10mm (1cm x 1cm), with triple-layer NiCuNi coating for corrosion resistance and a smooth scratch-resistant surface
• FITS 1/2-INCH COPPER TUBE FOR PHYSICS DEMOS: The 10x10mm cylinder drops into a half-inch copper or aluminum tube for Lenz's Law and eddy current experiments — drop-tower geometry for STEM kits
