Please understand sometimes there is a slight color difference because of the light.

Buckyball can provide you with hours of entertainment, which means that buckyballs has the power to attract you to the game. When you're satisfied with the shapes you've formed or want to start creating other shapes again, you simply restore each magnetic ball to a ball, and then try to recreate more of the other shapes. You can spend a lifetime trying to create a variety of different shapes.

Educational Function
You can improve your intuitive perception of geometry and mathematics by buckyballs. Buckyballs can be used as an educational tool to learn combined with textbooks, so that you can have a better understanding of geometric knowledge from the theory and practice. Because geometry needs a strong space imagination, buckyballs as a teaching tool can effectively improve the performance of Geometry section.

Improve Creativity
Every day, in different environment, we must learn to adapt. A person's ability to adapt directly affects the success or failure of one's life. Most games and intelligence toys simply require you to compose a preset shape. But buckyballs can make you free to use the imagination, create various types of shapes at will.
The biggest feature of buckyballs is that you can control it almost completely. Other intelligence toys and models limit you to creating only two-dimensional or three-dimensional graphics. And some of the other bunches of balls limit you to just two-dimensional graphics or polygons. Because buckyballs gives you control over any plane, the shape you create will be as unique as yours. You can completely control buckyballs because buckyballs is made up of 216 magnetic balls, and each magnetic ball is actually a point.

Effective Stimulation of the Left and Right Brain
Buckyballs is indeed a magical intellectual toy. Buckyballs can stimulate and exercise your left and right brain at the same time,
Buckyballs can benefit you more than other types of intellectual toys. Each side of the brain is responsible for controlling the different functions and cognitive faculties of the body. The left brain is responsible for logical reasoning, mathematics and language, and it controls the muscles on the right half of the body. The right brain controls spatial imagination, creativity, facial appearance and visual recognition, while controlling the right part of the body. When you play buckyballs, you not only have to use space imagination and creativity, but also use your logical thinking ability and even mathematical knowledge. This will make it possible for you to exercise the left and right brain at the same time.

Decompression Effect, Magnetic Health Care Function!!
One of the big roles of Buckyballs is that you can release stress. Buckyballs's decompression is due to his structure.
Like other pressure-relieving toys, buckyballs can be deformed and distorted, allowing you to release emotions. Better than other toys, buckyballs is made up of 216 independent magnetic balls, you can force buckyballs those magnetic balls apart, and then perfectly combine them together

How to increase the magnetic strength of NdFeB magnets?

How to increase the magnetic strength of NdFeB magnets?

With the continuous development of science and technology, the application of magnetic power has been continuously deepened. Many users may be curious, how do permanent  magnet manufacturer  how strengthen the magnetic force, and which are the technical methods?
NdFeb Permanent Magnets Manufacturer – China Rare Earth Magnet Limited

There are two common methods that can strengthen the magnetic power of strong NdFeB permanent magnet: change the size and material. In terms of the size, if the contact area is large, the thickness is thin, then increasing the thickness of the magnet will have a great effect on the strengthening of the magnetic power. If the contact area is small and the thickness is relatively thick, then the increase of the contact area of the magnet will directly change magnetic force.

Speaking of changing the material, NdFeB magnetic material is divided into various material grades. If the dimensions of the magnet are strictly limited, changing the material grade will be a feasible option.

Due to varying unanticipated circumstances, strong magnets may lose their magnetic strength over time, which render the magnets not strong enough and suitable for original application. What should we do to re-enhance the magnetism of the powerful magnets? Below are methods from NdFeB magnets  manufacturer:
1. The easiest way is to re-magnetize the magnets to their full magnetized condition.
2. Using magnet circuit designing method to gather magnetic flux in the yoke to generate strong suction.
3. To concentrate the magnetic line of force: absorb an iron plate the magnets and a higher magnetic field can be generated on the edges of the iron
4. To cover the magnets with a steel housing and only expose one contact area of the magnets and concentrate all magnetic power on the contact area

NdFeB Magnets Applied in Wind Power Motor 20170901

NdFeB Magnets Applied in Wind Power Motor 20170901
Penetration rate of direct drive motor has broad space of growth.
Generators of wind turbines mainly include double feeding and direct drive motors. Direct drive generator sets are driven by multi-pole NdFeB motors directly linking with impellers, without using traditional gear box. Generators will be more efficient and have smaller polar distance, if they employ rare earth permanent magnet motor technology, therefore, PM direct drive motors become major trend of technical development in the future, with gradually rising penetration rate in wind power sets.
NdFeB Motor Magnets

In 2016, new installed capacity of global wind power sets reached 546.42 million kilowatts, among which penetration rate of direct drive motor was 35%. 0.67kg of NdFeB magnets were applied in installed capacity of per kilowatt. According to this calculation, 1275 million tons of neodymium magnets were globally used in wind power sets in 2016. Based on estimation, by 2021, installed capacity of newly increased wind power send will reach 750 million kilowatts; therefore, growth rate of newly increased installed capacity is 6.5% in the world. Suppose that in 2017 and 2018, penetration rate of PM direct drive motor of wind turbines rises by 1%, then 1396.7 million tons and 1528.7 million tons of sintered NdFeB permanent magnets will be used in wind power worldwide, with year-on–year growth rate of 9.54% and 9.46%.

    Shape: Ring
    Size: as per customers’ requirements
    Grade: BNP-8, BNP-10, etc.
    Coating: Black Epoxy
    Magnetized with 4 poles through outer diameter or more multi-poles

    Surface Fields
    It is subject to the actual value in test. If the tester uses different Gauss meters to measure the same permanent magnet, the test value is different and the difference can be 200~300GS. For example, the Gauss value tested by our domestic equipment is about 1200 GS, while tested by Japanese Gauss meter the value can over 1300GS.

    Magnetizing Waveform
    For bonded ring NdFeB magnets used in motors, surface field is just one factor, and the most important factor is the magnetizing waveform. Some are very standard square waves, if the surface fields can not reach a value simply by upgrading the grade, a new fixture need to be made to improve the surface gauss value. It will take 7 working days to develop a new fixture. It will take about 12-15days to provide samples after finishing new tool. Our technicians suggest test the performance of the motor after equipping with magnets.

    As a responsible Bonded NdFeB permanent magnets manufacturer, China Rare Earth Magnet Limited always suggest customers require a few samples for testing before placing the 1st bulk order.
