• How to protect Neodymium Stong Magnets from corrosion

    Surface Treatment of Neodymium magnets

    Corrosion Resistance of Neodymium magnets

    A neodymium-based sintered magnet is liable to oxidization or corrosion because it has for its main components neodymium (Nd) and iron (Fe) and is composed of several phases in a crystalline structure. It is subject to electrochemical corrosion under the presence of a small amount of acid, alkali or water; the magnet rusts and demagnetizes as rusting progresses. Although it remains stable for many hours when it is allowed to stand in a dry atmosphere, it should be surface-treated as a preventive measure for the presence of humidity or a rise in temperature, an event often encountered in a general operating environment. This treatment may become unnecessary when it is used in a hermetically sealed system or in a low-corrosion environment.

    The magnet does not corrode when exposed to general organic solvents or adhesives. However, customers are advised to contact Magpole Technology sales office beforehand if cutting or grinding of any neodymium magnets products is intended. If washing and drying process is involved in processing of the neodymium magnets on the customers side, cautions must be undertaken concerning residual water or condensation of moisture on the magnets. Storing the magnets in a dry atmosphere or in an inert gas is strongly recommended.

    Surface treatment of neodymium magnet

    Neodymium magnets has improved corrosion resistance of the base material itself as a result of structural refinement and compositional uniformity of sintered constituents. Moreover, its reliability is enhanced considerably by the application of surface treatment technologies such as aluminum and nickel coatings. Additionally, greater importance is attached to surface coatings in terms of not only corrosion-resistance performance but also other factors such as adhesive durability and electrical insulation quality, the recently increasing requirements for magnets used in motors. We have developed environmentally sound processes and products that meet these requirements. Customers may use the neodymium magnets products with confidence with regard to these aspects. Our surface treatment technology is in compliance with international environmental standards, such as the RoHS directive and ELV directive.

    Customers are strongly advised to consult with Magpole Technology sales office for technical assistance concerning the surface treatments in order to choose appropriate treatment processes and product types suitable for the intended applications according to the specific usage environment and required characteristics.

  • How to Make a Cube out of 125 Supraballs

    Sidekick edition of buckyballs has 125 ball magnets in the box.

    Do you know how to make a cube with these 125 pcs spheres magnets?
    Here let’s show the basic way:
    buckyballs magnets 125
    Step 1 – Pull all 125 of your Buckyballs into a straight line.
    Step 2 – Count 25 ball in and fold so that each ball lines up perfectly with it’s neighbor.
    Step 3 – Now turn the chain the other way and zip it down again. Do it 2 more times, and the shape you’re left with is a sheet of Buckyballs 5 x 25.
    Step 4 – Count five balls in and fold the sheet, lining up the balls just like you did when it was a chain you were folding.
    Step 5 – Now fold the other way. Two more folds and you’ll have made the cube. There’s not a trick to it really, but be careful; one wrong move and you could be starting over. Buckyballs are like that.

  • Uses of Neodymium Magnets from Supramagnets

    Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals, also known as NdFeB, NIB, or Neo magnet), the most widely used type of rare-earth magnet. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet made. They have replaced other types of magnet in the many applications in modern products that require strong permanent magnets.

  • Fun Magnets Facts for Kids on Supramagnets

    Fun magnets facts for kidsFun Magnet Facts for Kids

    Learning about magnets is great fun. Magnets are used every day all over the world. Supramagnets try to find fun magnet facts for kids and enjoy learning some truly magnetic information about the world of magnetism.

    Let’s find out what a magnet is, how magnetic fields work, which metals are magnetic and which aren’t, how the Earth’s core relates to magnetism and much more. Use our fun magnet facts to start learning how magnets work.

    • Magnets are objects that produce an area of magnetic force called a magnetic field.

    • Magnetic fields by themselves are invisible to the human eye.

    • Iron filings can be used to show magnetic fields created by magnets (such as in the picture to the right).

    • Magnets only attract certain types of metals, other materials such as glass, plastic and wood aren’t attracted.

    • Metals such as iron, nickel and cobalt are attracted to magnets.

    • Most metals however are not attracted to magnets, these include copper, silver, gold, magnesium, platinum, aluminium and more. They may however magnetize a small amount while placed in a magnetic field.

    • Magnetism can attract magnetic objects or push them away.

    • Magnets have a magnetic north pole and a magnetic south pole. If the same pole of two magnets are placed near each other they will push away (repel), while if different poles are placed near each other they will pull together (attract).

    • Magnetic objects must be inside the magnetic field to respond, which is why you may have to move a magnet closer for it to have an effect.

    • The Earth’s core is believed to be a mix (alloy) of iron and nickel, giving the Earth its own magnetic field.

    • The Earth’s magnetic field is responsible for deflecting the solar wind, charged particles that come from the Sun.

    • Magnetic compasses use the Earth’s magnetic field to help navigate in north, south, east and west directions.

    • Electromagnets are created by an electric current running through a surrounding coil. They have many uses including the generation of electricity in hydroelectric dams.

  • High-precision automotive magnetic position sensor is immune to stray magnetic fields (AS5161-HSOP-500)

    AMS is a global leader in the design and manufacture of high performance analog ICs.
    The AMS AS5161 is a contactless Hall-based automotive magnetic position sensor designed for accurate angular measurement over a full 360 degree turn. A sub-range can be programmed to achieve the best output characteristic for the application. A simple diametrical 2-pole magnet rotating on the centre of the IC is required. The magnet may be placed above or below the IC.



    The AS5161 is a compact integrated solution which provides the absolute angle measurement with a resolution of 0.09 degrees over a full revolution as PWM output signal. The internal 14-bit core of the AS5161 enables a new programming of the start and stop positions with a resolution of 0.02 degrees to allow the finest system mechanical adjustments. High level of flexibility is assured by the programmability through the UART interface shared with the output pin, to reduce the number of pins in the application. The angular output data can be linearized in the final production to further increase the precision of the measurement. With embedded over-voltage protection and reverse battery protection, the AS5161 can fulfil the most demanding automotive safety standards.

    Typical applications include transmission gearbox position sensors, valve position sensing, contactless potentiometers and chassis ride height control.
