Types of Temporary Magnets and What They are Used For What is a temporary magnet? Temporary magnets are made from soft metals, and only retain their magnetism while near a permanent magnetic field or electronic current. They become magnetized in the presence of a magnetic field. They lose their magnetism gradually when the magnetic field [...]
What is a Temporary Magnet? The topic of magnets is a very intriguing one, to say the least. While scientists have not yet been able to explain the phenomenon of magnetic force and why it exists, there is plenty of information out there that can be taken in on the topic, including the different types [...]
How To Identify The Quality Of A Sintered NdFeB Magnet? Due to its cost-effectiveness, the sintered Nd-Fe-B neodymium magnet is widely used in many fields. Its applications include PC hard drives, magnetic resonance imaging (MRI), electric cars, magnetic levitation technique and consumer products like DVDs, mobile phones and speakers. Since it is required in nearly [...]
Cylindrical Permanent Magnetic Assemblies MPCO offers a wide variety of cylindrical permanent magnetic assemblies. Our assemblies come in alnico, ceramic, magnets with thru-holes, magnets with bolts and loops, and retaining magnets. Alnico magnets are ideal for high heat applications and Ceramic magnet assemblies are the most economical typically. Alnico refers to a type of iron [...]
Alnico Magnets Guide Alnico Magnets Info General Information Cast Alnico 5 is the most commonly used of all the cast Alnicos. This material is used extensively in rotating machinery, meters, instruments, sensing devices, and holding applications, to name a few. Excellent temperature stability, high residual induction, and relatively high energies characterize Alnico materials, composed primarily [...]
Neodymium Magnet Guide Neodymium Information Collectively known as Rare Earth magnets, Neodymium Iron Boron (NdFeB) and Samarium Cobalt (SmCo) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. NdFeB magnets are available in a number of different grades that span a wide range [...]
What are Neodymium Magnets A neodymium magnet are made from an alloy of iron, boron and neodymium. Neodymium magnets are the strongest type of permanent magnet commercially available. What are Magnet Grades? A magnet grade is a measure of the strength of a magnet and in most cases a higher number indicates a stronger magnet. [...]
Permanent Magnets Vs. Temporary Magnets When it comes to magnets, there are two main categories: classified as permanent and temporary. While the details and characteristics of temporary magnets were described in the previous section, permanent magnets are worth mentioning as well. In order to give you a better understanding of what exactly a temporary magnet [...]
Factors Affecting Suction Force of Permanent Magnets Many customers who came to inquire about the magnet’s attraction asked the most about how many Gauss can attract, or send a specification to ask how much it can attract. This is introduced in previous articles. If you are interested, you can click to understand. Today’s main Let’s [...]

Sintered Neodymium Iron Boron (NdFeB) Sintered Neodymium Iron Boron (NdFeB), or “neo” magnets, is the third generation of permanent magnet developed in the 1980s. It offers the strongest magnetic power today. With its excellent magnetic characteristics Neodymium Magnet offers flexibility for new designs or is replacing older materials like Alnico and Ceramic in many applications, [...]
Titanium Nitride Plated Magnets Medical industry is a relatively high-end application to the permanent magnets, especially in-body use. The FDA requires medical magnets must have approved biocompatible coating, thereby, parylene-coated magnet and Titanium Nitride coated magnet are generally served for this area. About Titanium Nitride Coating As the fourth transition metal nitrides, Titanium Nitride had [...]
