Circumferentially Oriented Magnets Circumferentially orientation and magnetizing pattern is not available for arc and ring magnets which comprised of Neodymium magnets and Samarium Cobalt magnets. The most common circumferentially oriented magnets are common Alnico horseshoe magnet, however, whether or not Alnico ring magnets can be oriented and magnetized through circumferential direction? In fact, Alnico ring [...]
Magnetic alloys are alloys engineered to have special magnetic properties. Permalloy Permalloy is the term for a nickel iron magnetic alloy. Generically, it refers to an alloy with about 20% iron and 80% nickel content. Permalloy has a high magnetic permeability, low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical [...]
Understanding Magnetic Permeability Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material's internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material's internal dipoles do not become easily oriented to an applied [...]
Encased Ceramic Magnets with Unthreaded Hole, Pot Magnet Ferrite Encased Ceramic Magnets with Unthreaded Hole - A case protects the magnetic material.

How linear motors work? In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. In an AC induction motor, electromagnets positioned around the edge of the [...]

Different Magnetism Materials, How different materials react to magnetism Scientists have a number of different words to describe how materials behave when you put them near a magnet (which is another way of saying when you put them inside a magnetic field). Broadly speaking, we can divide all materials into two kinds called paramagnetic and [...]
SIX Things to Know About Magnets Almost everyone knows these six basic facts about how magnets behave: 1, A magnet has two ends called poles, one of which is called a north pole or north-seeking pole, while the other is called a south pole or south-seeking pole. 2, The north pole of one magnet attracts [...]
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 [...]
Injection molded Neodymium magnets Besides sintered magnets and bonded magnets categories, injection molded magnet is one of the more important developments in magnetic materials, it has opened a new world of application opportunities. Similar to plastic injection molding, magnet injection molding process is by mixing the magnetic powder together with polymer binder, heated in the [...]
Injection molded ferrite magnets Injection molded Ferrite is another molding process of magnet category. Compared to injection molded NdFeB, the difference of injection molded Ferrite lies in different magnetic powder utilized, therefore injection molded ferrite has lower magnetic properties due to ferrite features, but it costs much less than that of NdFeB. Injection Molded [...]

What Are Non-Metallic Magnets? Non-Metallic Magnets - Scientists have suspected that graphene(a thin, single layer of pure carbon atoms) packed together in a hexagonal lattice structure and thought to be the future of aviation, isthe solution to creating a magnetic material able to hold onto its magnetism up to room temperature. Graphene is already well-known [...]
Modern permanent magnets are far removed from the traditional horseshoe magnets. Today, magnets are available in a variety of shapes to suit many applications, and the introduction of magnetic alloys and magnetic-oxide based ceramics has made the simple iron magnets the exception rather than the rule. Modern permanent magnets Advances in magnet technology [...]
