Abstract

Sealskin is used for the practice of cross-country skiing. In order to stick it to the ski one must use a special glue that is very sticky and hard to remove from the ski, and also it gets non-sticky if the glue is wet. In order to tackle this problem, a project has been submitted to the LQM laboratory in order to investigate a sealskin with nano-particle permanent magnets that will stick it to the skis. The aim of this report is to compare the eficiency, in terms of magnetic field generated by the magnets, of isotropic and anisotropic nano-particles of NdFeB. To do so, one will simulate, with the help of Ansys' Maxwell3D mode, three composition of magnetic powder : 100% isotropic particles, 100% anisotropic particles and 50% isotropic and 50% anisotropic particles.

Nanoparticle

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.

Neodymium magnet

A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially. Neodymium magnet are the most widely used type of rare-earth magnet. NdFeB magnets can be classified as sintered or bonded, depending on the manufacturing process used.

Magnet

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door.
