Adhesive Strong Magnet

Adhesive strong magnet is powerful Neodymium magnet with high quality 3M adhesive backing and a new, easy-pull tab. The neodymium magnet is Ni-Cu-Ni plated to protect them against corrosion and conventionally magnetized through the thickness. Usually, the magnets exist in two versions per size – the A version has a North Pole face visible; the [...]

Are Neo Magnets and NdFeB Magnets the Same?

Are Neo Magnets and NdFeB Magnets the Same? - We occasionally get inquiries and manufacturing prints identifying a custom magnet shape using the abbreviation Neo. Because shorthand works – both internally and in discussions with our customers – we likewise sometimes refer to a Neodymium magnet as Neo or NdFeB. Of the rare earth element [...]

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 [...]

Temperature Effects on Neodymium Iron Boron

Neodymium Iron Boron Temperature - Temperature Effects on Neodymium Iron Boron (NdFeB magnets) Temperature characteristics of NdFeB grades: The NdFeB magnets are the strongest magnets available. Up to +150 degrees C, they are stronger than the other Rare Earth magnet, SmCo. At around +150 degrees C and above these Neo magnets perform not as strongly [...]

How grade choice affects performance when the NdFeB magnet is subjected to heat

It is possible to demagnetise a Neodymium magnet by applying an external magnetic field in a direction opposite to the direction of magnetisation (DoM) of the NdFeB magnet. The extent of demagnetisation is a function of the total magnetic circuit (and hence the Intrinsic working point), the temperature (and hence the actual BH curve shape [...]

Pushpin Magnets FAQ

Pushpin Magnets FAQ Office&Work Place magnets Pushpin Magnets - Why are your magnets stronger than ordinary refrigerator magnets? The rare earth magnets we use are made from Neodymium, making them among the strongest permanent magnets available. Most refrigerator magnets use simple magnetized metal because it is far cheaper than Neodymium. Are magnets this [...]

High Temperature Magnet

We have developed new magnet for high temperature application! High Temperature Magnet - Neodymium magnet is with much higher Br than any other magnets such as AlNiCo, Sm-Co etc, but it also has a disadvantage, that its maximum working temperature and temperature stability are much worse than other magnetic materials, which directly restrict the wide [...]

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, [...]

Protective Coatings / Surface Finish for Neodymium Magnets

Protective Coatings Surface Finish for Neodymium Magnets A Neodymium magnet does not corrode and will retain its performance theoretically forever in dry environment (if not subjected to excessive heat, radiation or strong external magnetic fields). However, if it is placed in a wet environment, the result may be the opposite. The within-structure Iron [...]

Speaker Magnets

Neodymium speaker magnet Neodymium speaker magnet is the latest development in this industry, it’s not as expensive as Alnico but costs a bit more than ceramic magnet speakers. It has the advantages of both weighing about 50% less than other speakers and having stronger magnetic properties. Speakers made from neodymium magnet respond to [...]

What is a Neodymium Magnet?

Neodymium is the most powerful permanent magnetic material of which scientists are currently aware. It is also affordable, making it suitable for myriad applications. The chemical composition of a neodymium magnet is Nd2Fe14B, which is two atoms of neodymium, 14 iron atoms, and one boron atom. They are rare-earth magnets, in contrast to conventional ferrite [...]

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 [...]
