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 [...]
Magnetizing or Magnetization In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties [...]
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 [...]
Programmed magnets, Programmable Magnets, polymagnets, Correlated magnet pairs, Programmable Magnetized Magnet Programmable Magnets, Programmed magnets, or polymagnets are magnetic structures that incorporate correlated patterns of magnets with alternating polarity, designed to achieve a desired behavior and deliver stronger local force. By varying the magnetic fields and strengths, different mechanical behaviors can be controlled. Correlated magnet [...]
Apple using recycled rare earth elements in iPhone 11 Taptic Engine Apple is using recycled rare earth elements in the Taptic Engine Magnets of the new iPhone 11 and iPhone 11 Pro, according to Apple's Vice President of environment, policy, and social initiatives Lisa Jackson. The term "rare earth" refers to a set of 17 [...]
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 [...]
What Types of Welding Magnets Do You Need? Welding Magnets types - If you’ve watched a welder at work, chances are you seen him use a welding magnet. Welding magnets are very strong magnets that make great welding tools. They can stick to any metal surface and can hold objects at 45-, 90- and 135-degree [...]
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 [...]
How to Make Magnets Stronger Certain consumer products require magnetism to work properly; refrigerator magnets, some earrings, speakers, and so on. Magnets in each of these products require a strong magnetic field in order to attract and hold onto their respective objects. When these magnets become weak, they fail at their designated tasks. If that [...]
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. [...]
