What Are Neodymium Magnets Used For?
Neodymium magnets have an assortment of uses. Their strength comes from their rare earth composition, making them highly sought after magnets.
These objects come in all kinds of sizes and shapes, such as discs, bars, blocks or pots; some even feature threaded holes for quick attachment and fastening purposes.
They are used in electronics
Neodymium magnets have become an indispensable component in electronics, particularly hard drives and computers. Furthermore, neodymium magnets are widely employed for water treatment applications designed to decrease scaling from hard water sources, door locks that open/shut automatically upon contact and MRI scanners.
MRI scanners utilize large magnets to align protons in cells of the body in such a way that radio frequency waves can penetrate their tissues, producing detailed images of organs and interior parts of human bodies. They're even used by astronauts during space flights to maintain healthy muscular tone.
Computer electronics relies heavily on passive magnetic bearings as support mechanisms for moving parts without physical contact, or for energy transfer between components like in a motor or generator.
Magnetic levitation uses magnets to enable relative motion with minimal friction and wear on mechanical components, making the experience of relative movement smooth and cost-efficient. Magnets can also be found in escalators, wind generators, and magnetic resonance equipment.
Neodymium magnets are created using an alloy composed of neodymium, iron and boron. Their construction involves various processes - sintered and bonded processes among others - which may produce powerful magnetic forces.
Sintered magnets are created by vacuum-heating raw rare earth metal particles, then grinding, shaping and compressing them before plating with nickel, copper or zinc as a protective measure against corrosion.
Bonded neodymium magnets are formed from powdered neodymium mixed with iron powder and bound together using magnetic materials, such as ferrite. These bonded magnets may offer greater durability and possess lower curie temperatures than sintered versions.
Neodymium magnets can be formed into various shapes through injection molding and extrusion manufacturing techniques. They can be used to produce jewelry, tools, and baby strollers.
These rare earth magnets are also highly popular among craft projects involving modeling; in fact, they're one of the most commonly used rare earth magnets for these purposes.
Due to their extreme strength, neodymium magnets should always be out of children's sight when around. Swallowing one can obstruct both respiratory and digestive tracts resulting in serious health concerns for them as well.
They are used in home improvement projects
Neodymium magnets can be utilized for many different home improvement projects. From holding items together (like in a spice rack or knife holder) to aiding organization and display purposes ( such as for an art gallery display). Furthermore, these powerful magnets are great for hanging pictures or fixing furniture!
Neodymium magnets have many commercial and industrial uses, from antilock braking systems in automobiles to creating an internal magnetic field within an MRI scanner. Although these are the two primary applications for these magnets, there are countless others as well.
These magnets, commonly referred to as Neo, NdFeB or NIB magnets are the strongest permanent magnets available today and boast higher remanence and coercivity ratings than alnico magnets as well as an energy product much greater than any alnico model could deliver.
Neo magnets are composed of an alloy composed of neodymium, iron and boron in a tetragonal crystal structure forming a strong magnetic pull due to their composition - this has an impact on their strength and magnetic properties.
Sintered neodymium magnets are among the most widely-used varieties, offering exceptional remanence, coercivity, and energy product - ideal for applications requiring strong yet powerful magnets.
Compression-bonded neodymium magnets, also crafted of neodymium iron boron, can be found in small motors, electronics, and vehicles for flexible magnetic strips. Their manufacturing involves powder refinement combined with plastic materials before being compression molded for final production.
Neodymium magnets can be protected against corrosion by coating them with various materials, such as nickel, copper, zinc or tin. This process makes it more difficult for their magnets to deteriorate but may be costly to produce.
An alternative approach is using neodymium magnets in an installation known as "Hydro-Soft," wherein these neodymium magnets are placed over any type of plastic or copper pipe and powered by water flowing through these pipes.
They are used in craft projects
Neodymium magnets are one of the strongest and most widely-used permanent magnets. Commonly referred to as NdFeB magnets or Neo magnets or NIB magnets due to being composed of neodymium (Nd), iron (Fe) and boron (B).
Neodymium and ceramic magnets can be an excellent addition to craft projects. Their use is simple and can add some fun and interest to your home decor.
Neodymium magnets make crafting with them simple and effective; you're bound to create something one-of-a-kind you'll cherish for years! Create magnetic frames for photos you treasure or display your small air plants on decorative bug magnets!
Craft projects using neodymium magnets include making small terrariums for succulents and air plants using them as magnets, which make these beautiful displays easily achievable and look beautiful either on a refrigerator or filing cabinet.
Magnetic Terrariums can be an easy and cost-effective way to add color to your home or office environment, using simple materials available at hardware stores such as small containers and magnets.
Neodymium magnets aren't just useful for craft projects; they play an integral part of science and technology as part of the Rare Earth magnet family, boasting some of the strongest magnetic properties among any permanent magnet.
Neodymium magnets may be strong, yet difficult to manipulate and require special handling procedures for safe use. Furthermore, these powerful magnets present a choking hazard for children; swallowed magnets could adhere to intestinal walls causing serious health complications that require emergency surgery if swallowed whole.
As they're highly susceptible to the environment, neodymium magnets must never be exposed to water or humidity, nor stored in damp environments, as this could cause them to corrode over time and render them useless.
Neodymium magnets sold at hardware stores may be coated with zinc, gold or nickel plating to protect them from the elements. Although this helps prevent corrosion, its effectiveness cannot be guaranteed since iron in neodymium magnets quickly oxidizes and rusts over time resulting in their breakdown or degradation over time.
They are used in medical devices
Neodymium magnets have many applications within medical devices. As permanent magnets, they can be found in applications like MRI technology, magnetic switches, blood separators, hospital water filtration systems, laboratory testing procedures, ventilators and insulin pumps - among many other uses.
Magnetic surgery devices are also utilized for magnetic surgery, and can be found in numerous surgical devices. Magnetic fields are effective at extracting foreign objects like metal pieces or food debris that could pose risks to patients. They can also help improve patient experience during laparoscopic procedures while aiding surgeons to more easily find tumors.
These magnets are constructed using an alloy of neodymium, iron and boron (NdFeB), with high strength and compact sizes making them suitable for medical equipment of various kinds.
Neodymium magnets can be produced using several chemical processes, and one such process involves melting and pouring NdFeB powders into a mold, whereupon it solidifies into its shape - this technique is known as injection molding.
Extrusion or hot pressing techniques offer another method for creating neodymium magnets. This process involves pouring thermoplastic compound into a mold before heating to an ideal temperature before being pressed through a die.
Sintered magnets are then given their final magnetic properties through a process called fritting, in an oxygen-free atmosphere, in order to produce green magnets with strong magnetic forces.
Radially aligned neodymium magnets are one of the latest offerings on the market and can be made using three separate manufacturing processes: anisotropic pressure molding, hot pressing backward extrusion and radial rotating field alignment.
Magnets are utilized in medical device production, from surgical tools and diagnostic instruments to other products like medical grade plastics. Their strong magnetic fields enable them to form devices of all shapes, sizes and colors - such as surgical tools.
Radiation therapy uses platelets as part of its cancer treatments to increase activity of platelets in areas free from tumors and decrease blood flow to tumors, speeding wound healing rates.
