What Magnet is Stronger than Neodymium?
It’s a common worry that a magnet won’t be able to support the load of the task you’re attempting to do because of its little weight. This perception is not accurate. Neodymium magnets, also known as neodymium rare earth magnets, are the strongest magnets in the world and are suitable for any project, regardless of their size. When you shop with ROBO Magnetic, you’ll find that our neodymium magnets are available in the greatest strengths, various shapes, and sizes to accommodate your specific requirements.
How Powerful Are Magnets Made From Rare Earth?
Magnets are essential in operating a wide variety of 21st-century electronics and home appliances. There are many various kinds of magnets, ranging from refrigerator magnets that are used to keep to-do lists to strong magnets that are used to generate magnetic fields that are then used by wind turbines to generate energy.
Alloying certain rare earth elements with other components results in producing the world’s strongest magnets, also popularly referred to as rare earth magnets.
But how powerful are rare earth magnets, and what characteristics give them their exceptional strength?
Measuring Magnet Strength
The comparison of magnet strengths shown in the table below was created using information from our experts. However, before looking at the strongest magnets, it is necessary to understand how magnetic strength is measured.
One of the most important indications of magnetic strength is the maximal energy product, which may be expressed as a value in mega-gauss-oersteds (MGOe). A magnet’s remanence and its coercivity are the metrics that are multiplied to get this value.
Remanence
Ferromagnetic substances need to be introduced into the magnetic field of an existing magnet for them to take on magnetic properties. After applying an external magnetic field, the magnet retains a certain amount of magnetism known as remanence. This magnetism is measured in Gauss.
Coercivity
The amount of energy necessary to make a magnetic material lose all its magnetism is referred to as the substance’s coercivity. It is a measurement that measures the magnetic material’s resistance to demagnetization, measured in Oersteds.
The Strength Of Rare Earth Magnets
Each magnet is given a grade, which, most of the time, indicates how powerful it is. For instance, the strength of a neodymium magnet of grade N42 is measured in MGOe, which is 42.
To help put the power of two popular classes of rare earth magnets into perspective, below is a comparison of how their strength stacks up against that of two common grades of other permanent magnets:
| Grade of Magnet | Maximum Energy Product
(MGOe) |
Composition |
| N42 Neodymium Magnet | 42 | Neodymium, Iron, & Boron |
| SmCo2:17 (Samarian Cobalt) | 28 | Samarium & Cobalt |
| Alnico-5 (AlNiCo Magnet) | 5.5 | Iron, Aluminum, Nickel, & Cobalt |
| Ferrite-8 (Ferrite Magnet)) | 3.5 | Ceramics & Iron Oxide |
| Grade Y (Magnetic Rubber) | 0.8 | Strontium/Barium, Synthetic rubber, & PVC |
Two of the 17 rare earth elements, neodymium, and samarium, are ferromagnetic, meaning they have magnetic characteristics that are intrinsic to them and can also be magnetized. To produce the most powerful magnetic alloys, these metals are extracted from the ground, processed, and mixed with other components such as iron, boron, and cobalt.
Magnets made of neodymium generally include one-third of neodymium and iron and boron as the other two primary components. Another rare-earth substance, praseodymium, can also be used as a rare-earth magnet with the neodymium in magnets. For this reason, magnets made of neodymium are often referred to as NdPr magnets.
Neodymium magnets are used in various technologies due to their high strength. These technologies range from mobile devices and laptops to motors used in electric cars. These magnets are the most popular option for usage in wind turbines due to their very high strength with their comparatively tiny size. This results in a substantial reduction in the overall weight of the turbine.
Samarium-cobalt magnets demonstrate great resilience to severe temperatures. These magnets are resistant to corrosion and can function in temperatures ranging from as low as -270 degrees Celsius to as high as 350 degrees Celsius. Consequently, they are useful in various applications, including those found in severe maritime environments and in technologies that operate at high temperatures. However, in most cases, samarium-cobalt magnets are replaced with neodymium magnets due to strength and weight.
The World’s Most Powerful Magnet
Neo magnets are ten times stronger than ceramic magnets. They are also the most powerful industrial magnets available on the market. A single Neo magnet can carry up to a thousand times its weight while weighing just a few grams.
Because neo-magnets are so strong, they must be handled with extreme care. Their strength may drive them to attract metal or each other, which may be unpleasant if your fingers get trapped in their path. Our neodymium magnet manufacturing collections are of various and are plated based on your requirements using nickel and many more.
