How to Magnetize and Demagnetize a Permanent Magnet Due to random orientation for micro magnetic domains, a permanent magnet usually does not provide any magnetic flux when it is produced. It needs to be magnetized to saturation for use. So how to magnetize a permanent magnet? The basic principle is using a coil, i.e. an [...]

MULTI-POLE MAGNETIC CIRCUIT COMPARISONS MAGNETIC CIRCUIT DESIGN SECTION 1: EXPLANATION Most permanent magnets have a direction of anisotropy, where the magnetic domains are forced into a single direction during the production of the magnetic material. The magnet must then be magnetized in the direction of anisotropy, but being one-dimensional does not mean that the location [...]
Magnet Concept Am area of the magnet, is the cross sectional areal of the magnet perpendicular to the central flux line, measured in sq.cm. at any point along its length. In design, am is usually considered the area at the neutral section of the magnet. B Magnet induction, is the magnetic field induced by a [...]
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 [...]

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.
