Cerium Effect on the Permanent Magnet Industry

While Cerium wasn’t linked to magnetism earlier, this rare earth element does have an influence on the permanent magnet industry. It is said that, it is higher than the influence of neodymium, dysprosium, samarium, or even terbium, which are used in rare earth magnets. This is because of a concept that we can call balancing. In other words, to reduce processing costs, miners should be able to sell rare earths that they mine. However, it is not possible always due to variations in demand and supply. Though interlinked, they’re independent factors and rarely meet!

However the importance of demand-supply balance shouldn’t and cannot be ignored, if the efforts should yield profits. Nowadays, dysprosium and neodymium business thrives, something that’s not usual for rare earth industry. Originally, lanthanum and cerium were considered important rare earth elements. However, mining to get neodymium for magnet market, results in huge amounts of lanthanum and cerium. This is now piling up and creating an imbalance in supply – demand.

Generally, there are two ways to restore balance. One is by creating demand by coming up with newer applications and the other is reducing price. As for reduction in pricing, market always responds overwhelmingly well. Over the last fifty years, rare earth mining has moved to China. Even so, the growth and scope of rare earth elements were due to their applications. With an excess pile of Cerium accumulating, it is highly important to come up with new and innovative applications for this rare earth element. Recent attempts often mimicked rehash of older ideas and new uses are not yet identified. It is important to come up with many uses for Cerium, closely followed by lanthanum, to get rare earth elements market back on track.

The Forthcoming of Cerium Shakes the Permanent Magnet Industry

While Cerium was not linked to magnetism earlier, this rare earth element does have an influence on the permanent magnet industry. It is said that, it is higher than the influence of neodymium, dysprosium, samarium, or even terbium, which are used in rare earth magnets. This is because of a concept that we can call balancing. In other words, to reduce processing costs, miners should be able to sell rare earth that they mine and not just what is wanted the most. However, it is not possible always due to variations in demand and supply. Though interlinked, they’re independent factors and rarely meet!

The importance of demand-supply balance shouldn’t and can never be ignored, if the efforts should yield profits. Nowadays, dysprosium and neodymium business thrives, something that is not usual for the rare earth industry. Originally, lanthanum and cerium were considered important rare earth elements. When mining to get neodymium for magnet market such as circular magnets with holes, huge amounts of lanthanum and cerium are also got as by-products. This is now piling up and creating an imbalance in supply – demand.

Generally, there are two ways to restore balance. One is by creating demand by coming up with the newer applications and the other is reducing price. As for the reduction in pricing, the market always responds overwhelmingly well. Over the last fifty years, rare earth mining has moved to China.

China intensifies economic instability of neodymium magnets in motors

Neodymium - one of the so-called rare earth metals - is an important element necessary for producing very strong permanent magnets. With a growing tendency for electrically powered automobiles magnet efficiency has become key to manufacturing high-powered electric motors. However, with China being responsible for 90% of the world’s production of neodymium and its strained economic relationship with Japan, the market situation has been quite unpredictable.

Up until the early 80s the strongest magnetic alloy had been samarium and cobalt. The development of neodymium magnets by General voice coil Motors provided a stronger, easier to manufacture, and more abundant alternative (in terms of natural deposits). With the current push to "go green" scientists and engineers are constantly concerned with solutions bringing both environmental advantages and convenient horsepower levels. With neodymium a 1kg adhesive permanent magnet is enough for an 80 horsepower engine - decent performance by today's standards. But with the prices growing tenfold in the wake of political instabilities there are alternatives being worked on.

In an attempt not to make itself dependent on China, Toyota started developing induction electric motors, which do not require permanent magnets - the source of the magnetic field are electromagnets. This solution, while less dependent on rare earth elements, has the serious drawback of requiring electricity to power the electromagnets in order to make the motor operational. This significantly reduces battery life and also makes the device itself bulkier.

With intensive research under way to develop strong permanent magnets (primarily by the ARPA-E program) there are prospects for a technological switch in the sector of electrically-powered vehicles. But given the current state of technology we are still very much dependent on neodymium and by extension on the political subtleties of commercial exchange.

Sintered and Bonded Neodymium Cylinder Magnets Are Available

Neodymium magnets are so strong that it takes effort and skill to pull one off a ferrous material. When two or more magnets are stuck together, one would have to slide rather than lift to separate them. Because of how hazardous these rare-earth magnets can get, some ordinary people leave them for engineers and technicians. The truth, however, is that small magnet can be used by ordinary people in their garages, workshops, homes or offices. Neodymium cylinder magnets are certainly good picks for home use. There have multiple user applications. Sintered or bonded, cylinder or disc Neo magnets are perfect for home use.

When a magnet is sintered, we say that it has been die-pressed and molded into shape. Neodymium, iron and boron powder is put in a multi-cavity die and then it is pressed to become finer. Then the mixture is tossed into a very hot furnace (sintering) to become rock-solid. During the die-pressing stage, a magnet’s direction of magnetization or orientation is set. So some isotropic magnets without a definite line of orientation or anisotropic magnets with a definite line of orientation are produced through sintering.
Sintered neodymium cylinder magnets such as n52 magnets can have between 30 to 52 MGOe and so they are very powerful. The other method of compression bonding entails mixing neodymium, iron and boron powder with special epoxy adhesive to bind and compress it into a die cavity without a magnetic field. So compression bonded NIB magnets are usually isotropic. Epoxy adhesive makes these pieces resistant to harsh industrial fluids. Because of their low machining expenditures and prices, compression bonded NdFeB magnets are the best picks for a range of applications. Many customers can attest to the fact that many cylindrical neo magnets for home use are tiny, powerful things. Some can even be half the size of a shirt button yet immovable when stuck to a ferrous object.
They are therefore easy to have around the home as they occupy a small room and will never hide another item beneath. Neodymium cylinder magnets are used to hold photos, receipts and other documents on a fridge or another metallic surface. They are also perfect to hold sheets of paper on bulletin boards. Many teachers use them for physics experiments or projects. To ensure that powerful items are ordered, one should consider reading the product description page. It will indicate the N-rating of a magnet or its grade.

For a really powerful experience with neodymium magnet, one should pick an N48 grade or over. Note that a cylinder magnet is often axially magnetized. Therefore its poles are situated in the middle of the flat sides. Another factor to consider is whether a magnet boasts a nickel coating or not. Thicker Nickel coating makes magnets stronger and durable. They will hardly shatter when collided with hard surfaces. A prospective customer should also find out the amount of small neodymium cylinder magnets they would receive for a given price. An internet-based store owner will certainly indicate the quantity of detail amid others such as size, pull force and usage directions.

Magnetic Applications in Astronomy

We already know that the earth is a huge magnet, so where does its magnetism come from? Is it ever since ancient times? How does it relate to geological conditions? What is the magnetic field in the universe?

We have seen brilliant northern lights at least in the picture. Our country has recorded the aurora borealis since ancient times. The aurora borealis is actually the result of the interaction between the particles in the solar wind and the geomagnetic field. The solar wind is a high-energy charged particle stream emitted by the sun. When they reach Earth, they interact with the Earth's magnetic field, as if an electric wire were acting in a magnetic field, causing the particles to move and gather toward the North and South Poles, and collide with the rarefied gases above the Earth, resulting in the gas molecules being excited to emit light.

Sunspots are very intense areas of magnetic activity on the sun. The outbreak of sunspots can have an impact on our lives, such as temporarily disrupting radio communications. Therefore, it is important for us to study sunspots.


Geomagnetic changes can be used to explore deposits. Because all materials have strong or weak magnetism, if they gather together to form a deposit, then it will inevitably interfere with the geomagnetic field in the vicinity of the region, making the geomagnetic anomaly. According to this, the magnetism of the earth can be measured on land, in the ocean or in the air, the geomagnetic map can be obtained, the magnetic anomaly area on the geomagnetic map can be analyzed and further exploration, often unknown mineral deposits or special geological structures can be found.


Rocks with different geological ages often have different magnetic properties. Therefore, the geological age and the crustal movement can be judged by the magnetism of the rocks.

Many mineral resources are symbiotic, that is, several minerals are mixed together, they have different magnetism. Using this feature, magnetic separators have been developed, which use different magnetic properties of minerals with different compositions and different magnetic strength to attract these substances. Then the attraction of these substances is different. As a result, the minerals with different magnetic properties mixed together can be separated and magnetic separation can be realized.
