CMS MAGNETICS NB035-AD-1 N45 3x.5x.25 in magnet with 3M adhesive 33 lbs pull

Single-piece N45 bar magnet

This N45-grade neodymium bar magnet measures 3 x .5 x .25 inches and delivers a pull force of about 33 pounds. It arrives as one piece with a pre-applied 3M double-sided foam adhesive for immediate mounting. The magnet is magnetised through the .25-inch thickness so the poles sit on the two 3 x .5-inch faces. A triple nickel-copper-nickel coating protects the rare-earth material from corrosion.

Makers needing strong, thin holding power

The compact profile suits crafting, school projects, DIY fixtures, science demonstrations and research setups where a flat, high-strength magnet must bond to a surface without mechanical fasteners. Buyers who require multiple magnets in a pack, a different grade or dimensions, or a mounting method other than foam adhesive should look at other options. The brittle material can shatter on hard impact, so applications involving repeated snapping against steel are not a good fit.

3M foam adhesive enables tool-free installation

The supplied adhesive lets you press the magnet onto clean, flat surfaces without screws, epoxy or clamps, saving time in prototypes, displays or temporary fixtures. Because the adhesive is foam-based it also dampens vibration and accommodates slight surface irregularities. No additional hardware, coatings or software are included, so the only change to your workflow is the peel-and-stick step.
