The magnetization direction of neodymium disc magnets can vary depending on the manufacturer and the specific grade of the magnet. However, in general, neodymium disc magnets are magnetized through their thickness (i.e. from the top to the bottom or vice versa). This means that the magnetic poles are located on the flat circular surfaces at the top and bottom of the disc, and the magnetic field lines run in a circular pattern around the circumference of the disc.

Neodymium disc magnets are the strongest type of permanent magnets, making them suitable for heavy-duty applications where high magnetic force is required.
NdFeB magnets are highly resistant to demagnetization and can retain their magnetic properties for a long time.
Due to their compact size, neodymium magnets can be used in a wide range of applications, including industrial, commercial, and consumer products.
Compared to other types of strong magnets, neodymium magnets are relatively inexpensive, making them a cost-effective solution for many applications.
Neodymium magnets have a high energy density, meaning they produce a strong magnetic field in a small space. This makes them ideal for applications where space is limited.
NdFeB magnets can be small in size yet still have high magnetic strength, which makes them useful in applications where space is limited.
Neodymium magnet plating and coating can be better adapted to some harsh environments, such as ultra-low temperature, high temperature and humid environment.
