Neodymium bar magnets, also known as neodymium rectangular magnets, neodymium block magnets, or simply strong bar magnets, are among the most powerful rare-earth magnets available. Crafted from high-performance NdFeB alloy at magnet4sale.com, these super strong neodymium magnets deliver magnetic flux densities of 11,500 to 14,400 Gauss, making them ideal for demanding applications.
These rectangular neodymium magnets come in versatile shapes and sizes—from compact 1/8" x 1/8" x 1/16" pieces to larger bars exceeding several inches—with options like cubes, countersunk holes for easy mounting, or basic plain designs. Often referred to as the name of a simple rectangular magnet, their block or bar form provides excellent directional holding power and a flat surface for secure attachment.
Strength varies by grade, with N52 neodymium magnets offering the highest pull force—up to the strongest commercially available. Small N52 rectangular magnets can achieve 2–15 LB pull, while larger ones, like the N52 4x1/2x1/2" bar, deliver up to 85 LB or more. These strong N52 bar magnets excel in industrial uses (magnetic separators, electric motors, lifting), DIY projects (tool holders, crafts, organizers), educational demos, and practical tasks like magnets for picking up nails in grass—perfect for sweeping up metal debris, screws, or nails from lawns, yards, or construction sites.
Environmental considerations are key: most operate reliably up to 80–150°C, but avoid the Curie point (310–380°C) to prevent demagnetization—higher-temp grades are available. For dry environments, nickel-plated versions perform best; in wet or humid conditions (including outdoor grass use), choose epoxy, plastic, or rubber-coated neodymium rectangular magnets for superior corrosion resistance (note: coatings may slightly reduce effective pull).
Affordable prices start at just $0.08 for small pieces, scaling to $20–$50+ for larger or specialized strong neodymium bar magnets, with bulk discounts often available.
Discover the full range of neodymium bar magnets and N52 rectangular magnets. Top recommendations include the compact N52 Neodymium Bar Magnet 1/8x1/8x1/4" (2 LB Pull) the heavy-duty N52 4x1/2x1/2" Bar (85 LB Pull), and coated options like the N52 Plastic Coated Block 1x1/2x1/4" for wet environments. Select the right grade, size, and coating to match your needs for maximum performance and safety.
