Neodymium Block Magnet - 4mm x 3mm x 1.8mm I N50

Magnetic Product Description: This rare earth magnet has a length of 4mm, a width of 3mm and a thickness of 1.8mm. It has a magnetic grade of N50 and a NiCuNi (Nickel) coating. These Rare Earth Block Magnets are also known as Bar Magnets due to their rectangular block shape. This small but strong magnet uses a powerful Neodymium Permanent Magnet has a magnetic flux reading of 6698 and a pull force of 505 grams. It is identified by the AMF magnet part number B-W3H1.8L4-N50 Uses for our rare earth block magnets: AMF rare earth magnetic blocks are ideal for many applications and practical uses. These Neodymium block magnets are excellent for picking up nails & screws, as stud finders and for metal separation. They are often used to build electric generators, tool or knife holders and in metal detectors. Due to the size and dimensions of these Neodymium block magnets, they are also popular in electronics manufacturing, hobbies and crafts. If you are in need of a greater pull-force or more heavy-duty, industrial style of block magnets see our other Neodymium Bar Magnets.
