Magnet neodimium: Perbedaan antara revisi

'''Magnet neodimium''' (juga dikenal sebagai magnet '''NdFeB,''' '''NIB''' atau '''Neo''') adalah jenis [[magnet tanah jarang]] yang paling banyak digunakan.<ref>{{Cite web|url=http://www.adamsmagnetic.com/blogs/2012/what-is-a-strong-magnet/|title=What is a Strong Magnet?|date=October 5, 2012|website=The Magnetic Matters Blog|publisher=Adams Magnetic Products|access-date=October 12, 2012|archive-date=2016-03-26|archive-url=https://web.archive.org/web/20160326224820/http://www.adamsmagnetic.com/blogs/2012/what-is-a-strong-magnet/|dead-url=yes}}</ref> Magnet ini adalah [[Magnet|magnet permanen]] yang terbuat dari [[Logam paduan|paduan]] [[neodimium]], [[besi]], dan [[boron]] untuk membentuk struktur kristal [[Sistem kristal tetragonal|tetragonal]] Nd₂Fe₁₄B.<ref name="Fraden">{{Cite book|url=https://books.google.com/books?id=W0Emv9dAJ1kC&pg=PA73&lpg=PA73&dq=%22neodymium+magnet%22+strongest|title=Handbook of Modern Sensors: Physics, Designs, and Applications, 4th Ed|last=Fraden|first=Jacob|publisher=Springer|year=2010|isbn=978-1441964656|location=USA|page=73}}</ref> Dikembangkan secara independen pada tahun 1982 oleh [[General Motors]] dan [[Sumitomo Metal Industries|Sumitomo Special Metals]],<ref name="Lucas">{{Cite book|url=https://books.google.com/books?id=y0Z9AwAAQBAJ&pg=PA224&dq=neodymium|title=Rare Earths: Science, Technology, Production and Use|last=Lucas|first=Jacques|last2=Lucas|first2=Pierre|last3=Le Mercier|first3=Thierry|last4=Rollat|first4=Alain|last5=Davenport|first5=William|date=2014|publisher=Elsevier|isbn=978-0444627445|location=|pages=224–225|language=|doi=|id=|display-authors=3}}</ref><ref>{{Cite journal|last=M.
