آهن ربای نئودیمیوم به آهن ربایی اطلاق میشود که در ساخت آن از عنصر نئودیمیوم استفاده شده باشد و این نوع آهن رباها خاصیت مغناطیسی بسیار بالایی داشته و در نتیجه قوی ترین آهنربا ها معمولا آهن رباهای نئودمیوم هستند. اندازه کوچک و در عین حال قدرت بالای آن خصوصیتی است که استفاده از این نوع آهنربا را در کارهای حساس با عملکردی مناسب مقدر کرده است.
این آهن ربای فوق قوی به شکل مستطیل با اندازه 29 × 19 میلی متر دارای خاصیت مغناطیسی قوی است و کاربرد وسیعی دارد. اما باید توجه داشته باشید که این آهنربا شکننده است و باید به صورت خشک و در دمای اتاق نگهداری شود.
Description:
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet. It 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. Because of different manufacturing processes, they are divided into two subcategories, namely sintered NdFeB magnets and bonded NdFeB magnets. They have replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as electric motors in cordless tools, hard disk drives, and magnetic fasteners.
Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume.
Higher values indicate stronger magnets. For sintered NdFeB magnets, there is a widely recognized international classification. Their values range from 28 to 52. The first letter N before the values is short for neodymium, meaning sintered NdFeB magnets. Letters following the values indicate intrinsic coercivity and maximum operating temperatures (positively correlated with the Curie temperature), which range from the default (up to 80 °C or 176 °F) to AH (230°C or 446 °F) Neodymium magnets are used in numerous applications requiring strong, compact permanent magnets, such as electric motors for cordless tools, hard disk drives, magnetic hold downs, and jewelry clasps.
