Magnet Thermal Aging

Magnet Thermal Aging What is magnet thermal aging? Even though we usually say “permanent magnet”, but magnets do not remain magnetism permanently. In general, permanent magnets are gradually demagnetized by the impact of heat variations. This behavior of magnet can be determined by total flux change over time for a given temperature, also known as [...]

Application Classification of Rare Earth Permanent Magnet

Rare Earth Permanent Magnet Application Classification based on Operation Principle Rare earth permanent magnet can be classified into five types according to its operational principle, includes Lorentz Force Effect, Ampere’s Circuital Law, Faraday’s Law of Electromagnetic Induction, Coulomb’s Law for Magnetism and other magnetic effects. Actually, each operational principle has extremely widespread application area. Lorentz Force [...]

Magnetic Halbach Arrays

Magnetic Halbach Arrays - MAGNETIC-BEARINGS & HALBACH ARRAYS A Halbach array is a special arrangement of magnets that 'directs' the magnetic field to allow high magnetism in particular locations and low magnetism in other locations. Magnetic Halbach Arrays There are a number of different assemblies and arrangements available. We can supply Halbach arrays [...]

Magnetic Pottery

Magnetic Pottery - Evidence of Earth’s magnetic field is all around us. Animals use it to navigate, the spectacular display of the Aurora Borealis is generated by it, even your compass pointing north—all possible because of this mysterious force. However, while we experience the benefits of the magnetic field on a daily basis (we wouldn’t [...]

New microscope technique offers a better way to measure magnetic field of individual atoms

New microscope technique offers a better way to measure magnetic field of individual atoms, IBM magnetic fields A team of researchers at IBM has developed a new way to measure the magnetic field of individual atoms that offers 1000 times the energy resolution of conventional techniques. In their paper published in the journal Nature Nanotechnology, the [...]

Magnetic Units of Measurement

Magnetic Units of Measurement Magnetic Units of Measurement - If the burden of two systems of measurement for common quantities (English vs. metric) throws your mind into confusion, this is not the place for you! Due to an early lack of standardization in the science of magnetism, we have been plagued with no less than [...]

Ferromagnetism

Ferromagnetism, magnetic domains Looking back to the beginning of our thought experiment, magnetic fields may only be produced by a current. Taking the definition of current as a flow of electrons, electrons orbiting an atom should create a current and thus a magnetic field! If every atom has electrons is everything magnetic? YES! All matter, including [...]

Magnets Maintenance and Care

Magnets, with the right maintenance and care, can last indefinitely. For information on how to look after your magnet, here are a few tips: Storage Storing a magnet correctly is one of the most important ways in which you can give your magnet a long life. All magnets can be stored together in one place, [...]

What Is Ferromagnetism?

Ferromagnetism Ferromagnetism is a property of a material in which particles called magnetic moments organize parallel to one another when there is a magnetic field. These particles remain in place even when the magnet is taken away. Magnetism occurs on an atomic level, with the field having a direct affect on the electrons [...]

How is Magnet Strength Measured?

A magnet is any object that produces its own magnetic field. The magnet strength of these objects can vary from imperceptibly weak fields to incredibly strong fields, depending on a number of characteristics. Magnets can be classed into two distinct groups: permanent magnets and electromagnets, and non-magnets can be defined as either ferromagnetic, paramagnetic, or [...]

Star Wars Day with you: The “Force” of Magnets

Every geek, science lover, movie enthusiast, and anyone not living under a rock knows that Star Wars Day is May the Fourth! Even if you don’t believe in Lucas’ mystical ‘force’, there is a very real invisible force that we encounter everyday-Earth’s magnetic force. Like the power of the Jedi and Sith, magnetic fields are [...]

Rare earth magnets for fun and profit

One can academically appreciate the fact that every electric motor in the world (not counting a couple of very impractical ones) works because of magnetism. One can reflect on the fact that every transformer uses it, too. CRT monitors, TVs, brushless DC motors, power meters, modern welding gear and engine ignition timing systems, various vending [...]
