Is the N52 magnet the strongest? Are there any magnets that are stronger than N52 magnets? Are you curious about this question? Today, I would like to introduce you to the answer.
Ferrite and other materials may also be stronger than N52
Why is this? Listen to Fu slowly give you an introduction, N52 magnets are just a performance level of neodymium magnets, when the size is different, larger magnets will be stronger than smaller N52 magnets, this is because larger magnets have more magnetic domains, which can provide greater magnetic flux. As a result, larger magnets may exhibit stronger magnetic field effects in certain application scenarios, even when the magnetic energy product is lower. For ferrite magnets, although their magnetic energy product is much lower than that of NdFeB magnets, by increasing their size, they can produce a stronger magnetic field in a localized area to meet specific needs.
For example, large size ferrite magnets are often used in industrial magnetic separation equipment. Although their magnetic flux density is lower than that of N52, their overall magnetic force can exceed that of the smaller N52 size due to their larger size.
N54 or N55 magnets will also be stronger than N52
Yes, today there are higher grades than N52, such as N54, n55. n54 magnets have a magnetic energy product of about 54 MGOe, which is about 4% higher than N52. This means that for the same volume, N54 magnets are able to produce a stronger magnetic field. n55 magnets have a magnetic energy product of about 55 MGOe, which is about 5.8% higher than n52.

In addition, by designing a multi-layer or combined magnet structure, the magnetic field strength can be enhanced in a localized region. For example, stacking magnets of less than N52 grade with the same poles relative to each other produces a stronger localized magnetic field. Magnetic field strength can also be effectively amplified in specific regions using magnet array designs, such as Hastelloy arrays, which can achieve a stronger magnetic force than a single N52 magnet for the same volume.
In practice, the selection of suitable magnets should not only take into account their magnetic energy area, but also the size, shape, cost and environmental adaptability.
Summary: Under the same size conditions, there are relatively few cases where the individual magnetic energy product of commercially available magnets exceeds N52.
