Rectangle rare-earth magnets with a large surface area and a relatively slim profile of 3 mm thick. Provides a good balance of pull force and discreet thickness to slid underneath fabric without creating too much of a bulge.
Use it on or underneath paper, cardboard or even thin plastic according to your project requirement. Sufficient magnetic force can be felt thru thin material approximately below 3.5mm. For stronger magnetic force across thicker materials or gaps above 3.5mm, recommend using magnets with a thickness of 3.5mm and above.
Applications: Motors, Generators, NdFeB Pot Magnet, Speakers, Sensors, Earphones and other musical instruments, Magnetic therapy devices, Magnetic Chuck, Magnetic bearings and couplings, and many other magnetic applications.
Good to know! A neodymium magnet, the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the composition of NdFeB tetragonal crystalline structure.
What does the N35, N40, N42, N45, N48, N50, N52 grade mean? Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.
