Magnetiske materialer som tilhører klassen ferromagneter og ferrimagenter viser en sterk tiltrekning i et magnetfelt. Svak tiltrekning er karakteristisk for paramagnetiske substanser og svak frastøting for diamagnetiske.Slike stoffer regnes ikke med blant magnetiske materialer, siden alle materialer har en form for magnetisk respons når et ytre magnetfelt er til stede En magnet er et objekt som omgir seg med et magnetisk felt.Den kan være en laget av et ferromagnetisk materiale slik at den har en permanent magnetisering eller den kan være en elektromagnet som er avhengig av en elektrisk strømforsyning.Fysiske fenomen forbundet med magneter omtales som magnetisme som igjen er forklart ved elektromagnetisk teori De mest almindelige magnetiske metaller (kort fortalt) Jern (Fe) er det mest almindelige metal anvendt til magneter. Rent jern er let at magnetisere, så det kan skabe store magnetfelter. Neodymium (N) er det stærkeste magnetiske metal, der findes. Det er meget sjældent (findes i Kina og Canada) og derfor meget dyrt i forhold til f.eks. ferrit
Neodym er et skjørt materiale og er mindre korrosjonsbestandig. De er derfor vanligvis belagt med nikkel. Neodymmagneter kan leveres som blokker, ringer eller som skiver. Ferritt. Ferrittmagneter kalles også keramiske magneter fordi de er harde og skjøre, som porselen magnet materialer og sammensetninger.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field
Magnetisme er en egenskap ved et materiale som gjør at det tiltrekkes eller frastøtes av et annet materiale. Magnetisme er velkjent fra hverdagen, og man bruker magneter til mange praktiske ting. De fleste kjenner godt til kjøleskapsmagneter som holder papirer på plass, eller har en knivholder på veggen på kjøkkenet som fungerer ved hjelp av magnetisme Magnetisme er en kraft mellom elektriske ladninger i bevegelse. I en magnet er det mikroskopiske bevegelser av molekyler som gir opphav til magnetismen. Elektrisk strøm er ladning i bevegelse. I strømførende ledninger er det elektroner som beveger seg. Derfor virker to strømførende ledninger på hverandre med en magnetisk kraft. Det er vanlig å si at strømførende ledninger eller. Injeksjonsporten på brystimplantater av typen tissue-expanders kan bestå av magnetisk materiale, og MR-undersøkelse er kontraindisert. Meldeordningen ved Kunnskapssenteret, har fått melding om problemer i forbindelse med at det ble utført MR på en pasient med et brystimplantat med ventil som var merket med magnet Man sier at det er blitt magnetisert, og det kan brukes som en permanent magnet. Inneholder en ideell spole magnetisk materiale, vil det resulterende fluksfeltet inni spolen bli = hvis den fører strømmen I og har lengde L. Her er nå μ = μ 0 (1 + χ) den magnetiske permeabiliteten til materiale
NdFeB magnets Chemical composition: Chemical analysis for sintering NdFeB magnets material based on intermetallic compounds RE2Fe14B,main composition is NdFeB magnet is (RE), (Fe) (B),thereinto thulium (Nd), in order to obtain different performance can instead by thulium of (Dy),(Pr) etc. also other metal can instead Fe,for example (Co), (Al) etc., smaller content of boron, but it affect. A magnet forms when the magnetic dipoles in a material orient in the same general direction. Iron and manganese are two elements that can be made into magnets by aligning the magnetic dipoles in the metal, otherwise these metals are not inherently magnetic.Other types of magnets exist, such as neodymium iron boron (NdFeB), samarium cobalt (SmCo), ceramic (ferrite) magnets, and aluminum nickel.

Ceramic magnet material is a nonmetallic compound of iron oxide, strontium ferrite and small quantities of other metal oxides. The compound is calcined wet ball milled to a fine particle size, binders are added, then the mix is compacted in a press Also known as permanent lifting magnets, these magnets hold a load until you pull the handle and pry the magnet off. They have a lifting eye for attaching a hook or sling.. Style B magnets have a nonmarring roller release that prevents scraping and gouging the load as it is released..

Some Introduction of FePt Permanent Magnet Material Posted by sdm_admin In Techtalk FePt alloy has long been known as a very good kind of permanent magnet material, and FePt bulk has not applied well due to the expensive cost price, in the meanwhile, FePt permanent magnet material plays more and more important role with the development of magnetic recording media and nanotechnology The ITER magnet system will be the largest and most integrated superconducting magnet system ever built. Ten thousand tonnes of magnets, with a combined stored magnetic energy of 51 Gigajoules (GJ), will produce the magnetic fields that will initiate, confine, shape and control the ITER plasma. Manufactured from niobium-tin (Nb3Sn) or niobium-titanium (Nb-Ti), the magnets become. The material is then magnetized, laminated with vinyl or adhesive, cut to size, rolled onto a core, and boxed for shipment. Powerful - Magnet Source® flexible magnetic sheeting is supersaturated with magnetism in a multiple pole magnetization pattern, so its magnetic strength is evenly distributed across the surface component of B is greater inside the material with the larger permeability. Likewise, if you were to consider, for example, two different media lying side-by-side in parallel, between the poles, for example, of a horseshoe magnet, the component of B parallel to the boundary between the media i
