What Is Neodymium Ball Magnet and Its Advantage?

Commonly known as rare earth magnets, neodymium magnets are one of the most powerful types of magnet. The neodymium magnet is an alloy of 3 metals, namely boron, iron, and neodymium. They are available in various shapes and sizes. Neodymium magnets are used in many industries and are also called spherical. They offer users many options.
There are a few factors that need to be considered. The grade of the neodymium ball magnet is one of these factors. Regardless of its shape, each neodymium magnet sold over the internet has to be graded. The difference between the N-ratings needs to be known. The neodymium ball magnet is available from the N35 to N55. As the magnetic field of the magnet increases, the power increases. Anyone looking for the strongest neodymium ball magnet would need to get the N55.
Advantages of a Neodymium Ball Magnet
There are various advantages of a neodymium ball magnet. A highly rated magnet would have the highest energy product, remanence, and coercivity.
The neodymium ball magnet can work in a high amount of working temperature. However, a magnet with high coercivity would have to be used. Thus, it would not be easily demagnetized. The Curie temperature of neodymium magnets ranges from +200 to +230 degrees Celsius. Therefore, the neodymium ball magnet cannot be heated more than the stated range. When it comes to working with high temperatures, Samarium Cobalt magnets might be a better choice.
Neodymium offers optimal performance until it reaches over 150 degrees Celsius. It requires a plating layer or a special coating without which the neodymium ball magnet would rust. Hence, one needs to buy a spherical neodymium magnet which is coated or plated. It would ensure that the applications are indeed permanent.
Although spherical neodymium magnets are susceptible to corrosion, they do not need to be stored in a case or keeper. Since they are permanent, as long as the spherical neodymium magnets are used in the right environment, they will be very durable.
Neodymium magnet has many uses, due to its incredible strength. It is used in hard disc drives, audio equipment, bearings, jewelry, levitation devices, lifting machinery, magnetic resonance imaging (MRI) and much more.
Some of the advantages of neodymium ball magnets are as follows.
• Considered to be the most cost-effective choice when it comes to magnets used for industrial or commercial purposes.
• Has a high resistance to demagnetization.
• Offers the best power to weight ratio among all magnets.
Neodymium magnets have replaced ferrite and alnico magnets for various myriad application in modern technology where there is a requirement for strong permanent magnets. Their attraction is about a thousand times more than their weight.
