Cone shaped magnet is a special round magnet with different diameters of the two magnetizing surfaces, all cone magnets in this category are made of rare earth neodymium, and known as rare earth cone magnets or neodymium (NdFeB) cone magnets. Cone shaped neodymium magnets are custom magnets, we only list several cone shape neodymium magnets which are best sellers for most of magnet distributor, welcome you contact us for other  custom cone shaped neodymium magnets.

Types of Neodymium Cone Magnets

Neodymium Cone Magnet Features&Characteristics

Neodymium cone magnets are special axially magnetized disc magnets, cone magnets of neodymium are not rustproof, surface treatment needed from them. The power of neodymium cone magnets are range from N35 to N52. The magnetic line of force of the conical(cone) shaped neodymium magnet is bound on the smaller magnetic pole, which makes the neodymium cone magnet have very high magnetic adhesion.

Neodymium Cone Magnet Application

Cone(conical) shaped magnet is very suitable for office button magnet and used white board, metal strip or magnetic glass plate. You can use the smaller round surface to hold notes,  A4 paper, posters, etc. to the ferromagnetic surface. The special shape makes it easy to remove the powerful cone magnet from the side. When you use the larger magnetized surface of a neodymium cone magnet, then it is almost impossible to remove the cone magnet.If you are looking for other whiteboard magnets, you can find them in our office magnets.
