Magnets : Neodymium Magnets
Neodymium magnets are among the strongest permanent magnets available and have become indispensable components in TVs, speakers, generators, transformers and electric motors.
Electrolytic capacitors are used in hard disk drives, headphones and microphones to hold current-carrying coils that transmit electricity, as well as in rTMS therapy to treat depression. Their properties include high remanence and coercivity with a low Curie temperature threshold.
Neodymium Magnet Uses at School Home & Office
Neodymium magnets with strong magnetic forces are great additions to any home, school or office environment. They're great for keeping posters secure on a wall or keeping documents organized in folders or binders.
Magnets have also found wide application in information technology applications, including hard disk drives and mobile phones. Magnets also prove beneficial for magnetizing on/off switches and name badge magnets as well as magnetic separators, ionizers, Magnetic Toys and filters.
Neodymium magnets have long been employed in medical settings as an aid against chronic abiotic and biological inflammation, through magnetic compression anastomosis. Furthermore, strong magnets have also been proven to aid laparoscopic surgical procedures by acting as magnetic forceps that help remove unwanted tissue during laparoscopic surgeries - evidenced in studies with endoscopically identified colon tumors.
Neodymium Magnets in Industry
Neodymium magnets have long been utilized by various industries. From electric motor manufacturing and renewable energy applications, to medical science research and medical science research; neodymium magnets have many applications.
Neodymium magnet production begins by extracting its element from the ground, followed by its combination with iron and boron to form an alloy whose magnetic properties can then be adjusted through heating and cooling processes to achieve the desired results.
NdFeB magnets are used in hard disk drives to read and write data, as well as in MRI machines to produce strong magnetic fields for imaging organs and tissues. Furthermore, these magnets are found in smartphones and headphones as part of coils carrying current that converts mechanical energy into sound energy and produces sound waves.
Neodymium Magnet Shapes
Neodymium magnets are one of the most widely-used varieties of rare earth magnets. They are widely found in devices ranging from hard disk drives and car parts, to door catches and jewelry - even used on stage in magic tricks! Manufactured through either sintering or compression bonding processes, neodymium magnets allow complex magnet shapes such as bar magnets, discs, spheres, ring magnets, cube magnets & more to be created.
These devices come in various grades and shapes and sizes. Each grade possesses its own maximum energy product and Curie temperature range; N52 being one of the more frequently used grades. Some higher temperature versions feature letters after their grade number to denote their operating temperature range.
Neodymium can corrode in humid environments and should therefore be protected with nickel, copper, or zinc plating to ward off corrosion. Drilling this material must be avoided as heat generated can lead to demagnetization as well as remove any anticorrosive coating on its surface resulting in demagnetization and removal of its protective surface layer.
Neodymium Magnets The Strongest in The World
Neodymium magnets (Neo, NdFeB) are among the strongest permanent magnets commercially available, being over ten times stronger than ceramic(ferrite) and alnico magnets. Their impressive holding forces make them suitable for small spaces. Unfortunately, however, their fragility necessitates extra caution as even minor forces can break or chip them; hence they should always be handled with great caution.
Neo magnets have become an indispensable part of modern technologies; PC and laptop manufacturers, engine workshops and high tech devices rely heavily on them. Door catches, loudspeakers and microphones utilize them as strong magnetic fields which convert air pressure into sound frequencies. They're even used as current-carrying coils in door catches for door locks that secure them shut!
Rare earth magnets like neodymium offer excellent resistance to high temperatures, making them the go-to choice for electric vehicle motors. Unfortunately, their supply chain remains an issue as China accounts for most global production.
Where to Purchase Neodymium Magnets
Neodymium Iron Boron magnets come in a wide variety of shapes, sizes and grades. They're far less susceptible to cracking and chipping than ceramic (ferrite) magnets while producing significantly stronger magnetic fields.
Magnetic forcefields are used in an abundance of situations worldwide. You will likely come across them in your hard drive, cell phone and everyday electronics; oil filters, hardware machinery and toys all use powerful magnets; they even possess enough strength to manipulate electricity meters!
Neodymium magnets may seem extremely robust, yet they can demagnetize when exposed to high temperatures or damaged through direct contact with metals or external magnetic fields. Therefore, it is advised that they be handled with care.
