Introduction to Magnetic Materials

Introduction to Magnetic Materials A magnetic material is a material that can react to a magnetic field in a certain way. It is called a magnetic material, and generally consists of a transition element such as iron, cobalt, nickel, and alloys thereof, which can directly or indirectly generate magnetism. Magnetic materials are generally classified into [...]

About Some Magnet Knowledge

About Some Magnet Knowledge Permanent magnet material: The permanent magnet material is magnetized by an external magnetic field and does not disappear. It can provide a stable magnetic field to the external space. There are four common metrics for NdFeB permanent magnets: Remanence (Br) units are Tesla (T) and Gauss (Gs) 1Gs = 0.0001T A [...]

Explaining Magnetism

Explaining Magnetism with The Domain Theory In the early 20th century, before scientists properly understood the structure of atoms and how they work, they came up with an easy-to-understand idea called the domain theory to explain magnetism. A few years later, when they understood atoms better, they found the domain theory still worked but could [...]

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 [...]

Magnetic Material Classification

Magnetic Material Classification, The classification of magnetic material According to the magnetic  material under action of external magnetic field, the material is divided into anti magnetic material, anti ferromagnetic material, magnetic material. The latter two are strong magnetic material, magnetic material is widely used in science and technology. Magnetic materials classification generally divided into metallic [...]

Analysis includes material selection and optimization of [...]

Magnet Angle Deviation

Magnet Angle Deviation Due to the manufacture tolerances in pressing and machining of the magnets, the geometrical axle and magnetizing axle of the magnet usually are not parallel, but differ from each other with a certain angle. This is called angle deviation. Magnet Angle Deviation HSMAG can guarantee an angle deviation less than [...]

Magnetic Measurements

Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials response. [...]

Magnetic Working Point

Magnetic Working Point Magnetic Working point (Magnetic operating point) is a point, where the working line (load line) intersects the magnet's B-H demagnetization curve, and indicates the B and H state of the magnet in the magnetic circuit. Knowing the working point is essentia lasit makes possible to forecast the magnetic flux density Bd that [...]

Magnet Segmentation Technique

What is magnet segmentation technique? The magnet made by segmentation technology can be called laminated magnet, layered magnet, split magnet and segmented magnet. For magnet segmentation technology, the whole magnet will be segmented into several pieces, then processed into specific shape and dimension after glued together by special isolation glue. Magnet Segmentation Technique [...]

Magnets Attract African Kids To Science

Magnets Attract African Kids To Science - A postcard from Dr Graham Walker in Zimbabwe Magnets are quite extraordinary. Imagine, a special sort of rock that can stick to some things but not others, and sticks to itself one way but pushes apart the other. It's actually pretty weird when you think about it, and [...]

Permanent Magnet Stabilizing and Calibrating

Permanent Magnet Stabilizing and Calibrating Permanent magnets are utilized in a wide range of commercial and industrial applications, many of which require these magnets to function in a highly stable and consistent manner. Variables such as temperature, and demagnetizing fields will impact performance, but these effects can be mitigated through stabilization or calibration. Our new [...]

How are flexible magnets manufactured?

How are flexible magnets manufactured? - Flexible magnets are the same as ferrite magnets with the addition of synthetic rubber which makes them flexible. A ferrite magnet is an alloy made of strontium carbonate and iron oxide. Flexible magnets can be made in two different ways, either by extrusion, or calendering. The two different processes [...]

What is ‘Magnetic Therapy’?

What is 'Magnetic Therapy'? Put simply, it is the use of magnets to treat or ease the symptoms of various diseases and conditions, including pain. There are excellent articles on the Internet explaining and debunking magnetic therapy and we will provide links to some of these at the end of this essay. However we don't [...]

Researchers discover ‘superatoms’ with magnetic shells

Researchers discover 'superatoms' with magnetic shells, magnetic superatoms, magnetic moment, magnetic character, magnesium A team of Virginia Commonwealth University scientists has discovered a new class of 'superatoms' – a stable cluster of atoms that can mimic different elements of the periodic table – with unusual magnetic characteristics. The superatom contains magnetized magnesium atoms, an element traditionally considered as non-magnetic. [...]

Halbach Arrays

In industrial applications, a Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force applied. Halbach Arrays, both planar and circular, produce a magnetic field similar to what a powered solenoid (Electromagnet) would create, but without the [...]

What is a Halbach Array?

What is a Halbach Array? A Halbach array is a specific arrangement of a series of permanent magnets. The array has a spatially rotating pattern of magnetism which cancels the field on one side, but boosts it on the other. The main advantages of Halbach arrays are that they can produce strong magnetic fields on [...]
