Halbach Arrays

In industrial applications, a Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force applied. Halbach Arrays, both planar and circular, produce a magnetic field similar to what a powered solenoid (Electromagnet) would create, but without the [...]

What is a Halbach Array?

What is a Halbach Array? A Halbach array is a specific arrangement of a series of permanent magnets. The array has a spatially rotating pattern of magnetism which cancels the field on one side, but boosts it on the other. The main advantages of Halbach arrays are that they can produce strong magnetic fields on [...]

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 [...]

How to Recognize Neodymium Iron Boron Appearance Defects Correctly

How to Recognize Neodymium Iron Boron Appearance Defects Correctly NdFeB appearance defect detection of a correct understanding, is conducive to customer an objective understanding of this new detection technology. Equipment is not a panacea, but no equipment entirely rely on manual testing is a great risk, the long run, machine substitutions is an inevitable trend. [...]

How to re-magnetise an old magnet ?

How to re-magnetise an old magnet ? Re-magnetise Old Magnet Even if your magnet is kept in top condition, it can still become demagnetised during its lifetime. An example of this is a samarium cobalt magnet which has been shown to naturally lose 1% of its magnetic capabilities over a period of 10 years. [...]

How to avoid demagnetising magnet ?

Avoid Demagnetising Magnet Demagnetisation is the process whereby a magnet loses all of its magnetic properties. The magnet most prone to demagnetisation is the ferrite magnet due to the alloy it is made of, however all magnets can be demagnetised. To avoid demagnetising your magnet, follow these guidelines: Separating your magnets Make sure you separate [...]

Remagnetize a Magnet

Demagnetization is the reduction or elimination of magnetization. One way to do this is to heat the object above its Curie temperature, where thermal fluctuations have enough energy to overcome exchange interactions, the source of ferromagnetic order, and destroy that order. Another way is to pull it out of an electric coil with alternating current [...]

Low Weight Loss Magnet

It is the time for low weight loss neodymium magnet now! Low Weight Loss Magnet - The corrosion resistance of Neodymium magnet is considered poor, surface coating is highly recommended for Neodymium magnets. With the expansion of elevators, wind turbines and permanent motors application, the users need higher requirement on corrosion resistance of Neodymium magnet, [...]

5 Cool Objects That Float Using Magnetic Levitation

People can already travel by levitating, whether via maglev trains or the Hendo Hoverboard. So, engineers and scientists are making it easier to defy gravity within your own home as well. Magnetic levitation isn’t just for science experiments anymore. Now, you can find several cool objects that float using magnetic levitation. From toys and tools [...]

What Happens When a Magnet is Heated

What Happens When a Magnet is Heated ? Magnets can be found in many everyday items and technologies such as cars, phones and computers. It is because of permanent magnets' ability to create their own magnetic field that they are useful in various products and situations. However, they are not impervious. Magnet strength can be [...]
