An N52 magnet is a neodymium magnet with an energy product (BH)Max of 52 MGOe (Mega-Gauss Oersteds). The “N52” refers to its strength, making it the strongest neodymium magnet available.
Neodymium magnets are made from a mix of neodymium, iron, and boron, which gives them incredible magnetic power. There are other grades, like N35, N38, N42, N45, and N48\u2014the higher the number, the stronger the magnet. Since N52 magnets have the highest strength, they also tend to be more expensive than lower-grade magnets.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

N54 magnets are the most powerful N series neodymium magnets that can be mass-produced. However, N52 magnets are still often considered the most powerful permanent magnets for holding applications. With the increasing demand for higher magnetic flux density from magnetic separation and filtration producers, the mass production of N54 magnets has become feasible at some large-scale NdFeB manufacturers. Currently, many NdFeB manufacturers can produce these magnets in bulk. Since there’s no international standard yet, some people even refer to them as N55 magnets. Due to the lack of current international standards, some manufacturers and customers also use the name N55 magnet.<\/span><\/p>

The N55 magnet is currently one of the strongest magnets available for commercial use. Neodymium rare earth magnets are measured on a scale from 24MGOe to 55MGOe in terms of strength. This new grade of neodymium magnets is 5-6 percent stronger compared to the more commonly used N52 grade. The N55 grade of NdFeB represents the pinnacle of permanent magnet technology, with unmatched magnetic strength. While it may not be suitable for every application, the N55 grade offers distinct advantages in specific cases.<\/span><\/p>

These magnets are particularly useful in applications requiring maximum magnetic strength in a small space. Due to its powerful magnetic field, the N55 grade is ideal for precise and delicate work where size really matters. It is truly a super-strong magnet. For instance, the Magma engineering team used these high-power magnets in a newly developed magnetic bearing prototype, ensuring maximum efficiency and power through finite element analysis.<\/span><\/p>

The N55 neodymium magnet is one of the strongest magnets currently available for commercial use. The theoretical (BH)max value of the N55 NdFeB magnet is 512k\/m3 (64MG0e). While most magnet manufacturers can now produce N52 magnets, the (BH)max of N52 already reaches 90% of its theoretical limit. The N55 grade offers even stronger magnetic force, making it the most powerful commercially available grade today.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
