Giant Magnetoresistance

Giant Magnetoresistance Have you ever sat around on a rainy day contemplating your computer’s hard disk drive? Though often taken for granted, this magnetized device makes it possible to store and retrieve information digitally – in everything from video games to iPods to your personal computer. The first hard disk drives (HDDs) date back to [...]

Permanent Magnets: A Study in Sticktoitiveness

Permanent Magnets: A Study in Sticktoitiveness There are two basic kinds of magnets  permanent and temporary. We'll take on permanent first  which is appropriate, because before humans could invent and exploit temporary magnets, they had to discover the permanent kind first. People first happened upon magnets sometime before 600 BC with the discovery of the [...]

Hybrid Magnets: Best of Both Worlds

Hybrid Magnets: Best of Both Worlds Unlike most of the math that goes on at the Magnet Lab, the equation you need to make a more powerful continuous field magnet is pretty easy. Take a very powerful superconducting magnet  say, 11.5 tesla  and a very powerful resistive magnet  say, 33.5 tesla  and put them together. [...]

Electromagnets: Two Forces Team Up

Electromagnets: Two Forces Team Up Resistive electromagnets, another type of temporary magnet, combine the powers of electricity and of magnetism to enormous effect. Although superconducting electromagnets, which we'll discuss soon, offer many advantages, certain laws of physics prevent them from reaching the field strengths electromagnets are capable of. Some of the world's most powerful resistive [...]

Superconducting Magnets: Power Unplugged

Superconducting Magnets: Power Unplugged Superconductivity is a very cool phenomenon in which electrical resistance is overcome with the help of very cold temperatures colder than anything this side of Pluto! Most superconducting magnets are made using an alloy called niobium-titanium  "Ni-Ti" for short. You could think of it this way: In a superconducting current, the [...]

A Boost for Permanent Magnets

A Boost for Permanent Magnets Scientists at TU Darmstadt explored on an atomic level how changes in iron content influence the micro-structure of samarium-cobalt based permanent magnets. Their results were published in Nature Communications. In the long run they could contribute to the development of permanent magnets with improved magnetic performance. These magnets can be [...]

Scientists Discover Potential Path to Improving Samarium-Cobalt Magnets

Scientists Discover Potential Path to Improving Samarium-Cobalt Magnets Scientists have discovered a potential tool to enhance magnetization and magnetic anisotropy, making it possible to improve the performance of samarium-cobalt magnets. The scientists, at the U.S. Department of Energy's Critical Materials Institute at Ames Laboratory, in collaboration with the Nebraska Center for Materials and Nanoscience and [...]

A Breakthrough in Magnetic Material Surface Technology

A Breakthrough in Magnetic Material Surface Technology A few days ago, the magnetic material surface technical team of the Institute of Rare Earth Materials of Baotou Rare Earth Research Institute used the plasma spraying-grain boundary diffusion method to use heavy rare earth oxides to change the coercivity of the 50M magnet under the condition of [...]

How to Measure the Density of Magnetic Materials?

How to Measure the Density of Magnetic Materials? Materials that respond in a certain way to a magnetic field are called magnetic materials. According to the magnetic strength of the material in the external magnetic field, it can be divided into diamagnetic material, paramagnetic material, ferromagnetic material, antiferromagnetic material and ferrimagnetic material. Ferromagnetic substances and [...]

What is Ferromagnetic Paper?

What is Ferromagnetic Paper? Ferromagnetic paper is formed by impregnating ordinary paper or newspaper with "magnetic nanoparticles". It can be used to make low-cost "micro-motors" for surgical instruments, tiny tweezers to study cells, tiny robots and tiny speakers. At present, the researching people will also ferromagnetic origami paper, to study more complicated design. Ferromagnetic paper [...]

Basic Knowledge Of Magnetic Materials

Basic Knowledge Of Magnetic Materials About Magnetic Materials: Magnetism is one of the fundamental properties of matter. Magnetic phenomena are associated with various forms of charge motion. Magnetic fields are generated by the motion and spin of electrons within a material. All matter is magnetic. According to the magnetic nature of the difference can be [...]

The Difference Between Maximum Working Temperature and Curie Temperature of Magnet

The Difference Between Maximum Working Temperature and Curie Temperature of Magnet Maybe some people think the maximum working temperature of magnet is same as its Curie temperature. Actually, this is a mistake. The magnetic material can be divided into 5 kinds: ferromagnetism, ferrimagnetism, anti-ferromagnetism, paramagnetism, diamagnetism. Iron, Cobalt and Nickel are ferromagnetic material, also permanent [...]

Magnetic Chutes

Magnetic Chutes, High Intensity Magnetic Chute Separator Magnetic Chutes are used for trapping and separating iron particles mixed with dry, granular or powdered materials. They are generally used where flowing material characteristics are sticky and non free flowing. They come with either Conical Magnets fitted on hinged doors or Magnetic Plates fitted on the sides. [...]

How to make your magnetic separator work longer

How to make your magnetic separator work longer 1. Check before operation: 1.1 Whether the discharge scraper is in contact with the surface of the cylinder; 1.2 Whether the oil quantity in the bearing and reducer is appropriate; 1.3 Whether the bolts are loose or not; 1.4 The power supply has no faults; 1.5 There [...]

Magnet Attracting Repulsion Principle

Magnet Attracting Repulsion Principle Magnet Attracting Repulsion - Now more and more people are using magnets, we want to discuss some of the most basic issues with you first. How do magnets attract each other? How are they excluded? How to make the screwdriver magnetized? Magnet basics magnets can attract each other or repel each [...]

Magnetism

Magnetism Science is our understanding of how the world works—and generally the world works fine whether we understand it or not. Take magnetism, for example. People have known about magnets for thousands of years and they've been using them practically, as compasses, for almost as long. The ancient Greeks and Romans knew as well as [...]

How to use flexible magnetic sheet

Electropermanent systems by HSMAG

Electropermanent systems, electro-permanent magnetic system, electropermanent magnetic chucks Electropermanent systems by HSMAG - Electropermanent clamping systems are the combination of permanent and electromagnetic technology. They exploit the ability of some ferromagnetic materials to become a permanent magnet due to the fast action of strong direct current. In this state, they continue to function without the need of [...]

What are weld clamp magnets used for?

Weld clamp magnets are predominantly used to hold pieces of ferromagnetic materials in position for tack welding. arrow-magnetic-angle-weld-clamp Welding a tree shaped candle holder together with an arrow fixed multi angle weld clamp magnet. Tack welding is where a series of small welds are used to align pieces of metal securely before completing [...]

A forklift magnetic sweeper has been specifically created to fit onto a forklift truck. forklift magnetic sweeper There are two types of forklift magnetic sweeper: one with fork pockets and one with eyehole bolts. eye bolt and fork pocket forklift magnetic sweepers They are used to remove ferromagnetic materials from roads [...]

How does a permanent magnet work?

Permanent magnet work: Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron, which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons, orbiting around a positively charged nucleus. These electrons [...]
