Best Neodymium Magnets under $200

Full Description

The CMS Magnetics Neodymium Block (30x20x6 mm, N42H grade) is a high-performance rare-earth permanent magnet designed for industrial, commercial, and heavy-duty DIY applications. Built from Neodymium-Iron-Boron (NdFeB), this block magnet delivers an impressive magnetic field strength relative to its compact dimensions. The N42H rating signifies a high energy product combined with an enhanced temperature resistance, allowing the magnet to operate effectively in environments up to 120 degrees Celsius without significant magnetic degradation. Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that provides superior corrosion resistance and a smooth, professional finish. These rectangular block magnets are commonly utilized in engineering projects, magnetic separators, furniture manufacturing, and workshop tool organization.
