Here's the Actual Difference Between Paramagnetism and Diamagnetism Paramagnetism and diamagnetism are two distinct types of magnetic properties exhibited by the different elements in nature. Here, we shall learn more about each of them, and find out how they differ from one another. Levitation! The Radboud University Nijmegen, the Netherlands, conducted experiments where water and [...]
The Uses of Magnets Magnets, besides being fun to play with, have many uses. They are used in consumer as well as industrial goods. Let's get to know more about the uses of magnets. Magnets are materials which produce a magnetic field, and have the capability to attract ferrous components like iron, steel, cobalt, and [...]
Nanocomposite Permanent Magnet Materials Nanocomposite permanent magnet materials, combining magnetically hard and soft phases in nanoscale, is a new permanent magnetic material. Compared with traditional permanent magnetic material, nanocomposite lowers rare earth content and cost, exhibits high coercivity of hard magnetic phase and high saturation magnetization of soft magnetics phase, upgrades in temperature stability, heat [...]
How to Remagnetize Magnets Steel or ceramic magnets that have been stored incorrectly, dropped repeatedly or are simply old may lose their magnetic properties. For optimal results when it comes to rejuvenating these magnets, touch one pole to the opposite pole of a neodymium magnet. Obtain the Materials Obtain a neodymium magnet, which is made [...]
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 [...]
Magnetic Losses Reversible Magnetic losses are normal behavior for all magnetic materials. As the remanence of the all the magnetic materials decreases with increasing temperature, the temperature coefficient is negative, it is to be expected that the magnetic field of a magnet also will decrease with an increase of the temperature. However, this decrease of [...]
Differentiate Your Product Design with Polymagnets For products that can truly stand out in the crowd, Correlated Magnetics Research has developed a patented technology called Polymagnets. Product designers can tune the feel of a magnetic feature to evoke a specific emotional response with a sophisticated tactile feel in their product. Polymagnets are the only tunable [...]
Hard Magnetic Materials Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic material can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal [...]
Magnetic Alloys 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 [...]
Mounting magnets are comprised of powerful permanent magnets set inside steel cups or channels with countersunk holes or threaded features for holding applications. The steel structure redirects the magnetic field from the back-side of the magnet, making it much more stronger in terms of pull force, and protects the magnetic material from damage during use. [...]
Magnetic Simulation Magnetic simulation is the perfect design tool while approaching a complicated magnetic problem. With our know how, it can be used to achieve high level magnetic design. We can simulate and calculate special magnetic arrays, magnetic force (for example if you need a very unified magnetic field), torque and many more parameters. [...]
