Rare Earth Magnet Rod 2.5x7.5mm N42 Neodymium

Rare Earth Magnet Rod 2.5x7.5mm N42 Neodymium for Hobby and Lab

Need pinpoint magnetic pull along a length, not just a face? This 2.5 x 7.5mm N42 neodymium rare earth magnet rod is the right shape for the job — long enough to extend through layered materials, narrow enough to fit precision holes.

Cylindrical magnets solve problems that flat discs can't. Their elongated form factor concentrates magnetic flux along the rod's axis, making them ideal for stirring small lab samples, building rotating mechanisms, securing miniature drawer catches, or testing gemstones for ferrous content. This 2.5 x 7.5mm rod fits standard 1/8-inch drill holes and slides cleanly into press-fit assemblies. Built from N42 grade neodymium with a nickel-copper-nickel triple coating, it resists corrosion, holds its strength for years, and offers consistent magnetic performance across a wide temperature range. Geocachers, prospectors, model railroaders, and science teachers all benefit from having a few of these on the bench.
