Neodymium disc magnets are a type of rare earth magnet known for their exceptional strength and a wide range of applications. Here are some of the key features and characteristics of strong rare earth neodymium disc magnets:
Exceptional Magnetic Strength: Neodymium magnets are the strongest type of permanent magnets available. They can generate a powerful magnetic field, making them ideal for a variety of applications.
High Energy Density: Neodymium magnets have a high energy product, which means they can store a large amount of magnetic energy in a relatively small volume.
Small Size: Despite their strength, neodymium disc magnets are compact and lightweight. This makes them versatile and suitable for various design and engineering applications.
Versatility: These magnets come in various sizes and grades, allowing you to choose the right one for your specific needs. The N-grade or grade of a neodymium magnet indicates its strength, with higher numbers indicating greater strength.
Corrosion Resistance: Neodymium magnets are susceptible to corrosion, so they are often coated with nickel, zinc, or other materials to protect them from environmental factors.
Temperature Sensitivity: Neodymium magnets are sensitive to high temperatures, and their performance can be significantly reduced when exposed to temperatures above their Curie temperature (typically around 80-150°C, depending on the grade). Specialized high-temperature neodymium magnets are available for applications requiring exposure to elevated temperatures.

Diametrically magnetized disc magnets are magnets that have their north and south poles on the perimeter of the disc, rather than on the opposite faces. This means that the opposite sides of the magnet have alternating poles (e.g. north-south-north-south). Diametrically magnetized disc magnets have a unique magnetic field pattern that can be useful in certain applications. For example, they can be used in sensors to detect the rotational position of a shaft or wheel. When a diametrically magnetized disc magnet is placed on a rotating shaft, its magnetic field changes as it rotates, allowing sensors to detect the angle of rotation.
These magnets can also be useful in motor applications, as they can provide a more efficient use of magnetic field than traditional axially magnetized magnets. They also have higher resistance to demagnetization due to their unique magnetic field pattern.
Overall, diametrically magnetized disc magnets are a versatile magnets with a unique magnetic field pattern that can be useful in many applications.
