What are the characteristics of the magnetic field range of Cylinder Magnet relative to their shape?

The magnetic field range of Cylinder Magnet has some unique characteristics relative to their shape, which is mainly related to their cylindrical geometry and magnetization method. In the length direction, the magnetic field distribution of Cylinder Magnet is relatively uniform due to the symmetry of their shape. This uniformity allows the magnet to provide a relatively stable magnetic field strength at all positions in the length direction.
In the radial direction (i.e., the diameter direction), the distribution of the magnetic field may vary depending on the specific size of the magnet (such as the ratio of height to diameter) and the magnetization method. Generally speaking, when the height/diameter ratio approaches 0, the center field strength may be lower than the edge; when the ratio is much greater than 1, the difference in magnetic field strength between the center and the edge may not be significant.
Because the height (thickness) of the cylindrical magnet is greater than the diameter, this shape allows the magnetic field of the magnet to expand over a wider area. In particular, when the magnet is fully magnetized, its magnetic field can extend along the length direction and cover a longer distance. At the same time, the circular surface of the cylindrical magnet also helps the magnetic field to be evenly distributed within a certain range in the radial direction, thereby further expanding the effective range of the magnetic field.
Cylinder Magnet have the flexibility to be magnetized in either the length or diameter direction. This flexibility allows magnets to be customized to meet specific magnetic field distribution requirements according to different application needs. Different magnetization methods affect the magnetic field strength and distribution characteristics of the magnet. For example, magnetization in the length direction may make the magnetic field more concentrated and stable in the length direction, while magnetization in the diameter direction may make the magnetic field more uniform in the radial direction.
By adjusting the parameters of the cylindrical magnet such as size (such as height, diameter), material (such as high-performance permanent magnet materials such as NdFeB), and magnetization method, the magnetic field strength can be effectively controlled. This controllability makes the magnet suitable for a variety of application scenarios that require precise control of the magnetic field strength.
The magnetic field range of Cylinder Magnet is uniform, scalable, flexible, and controllable relative to its shape. These characteristics make Cylinder Magnet widely used in magnetic toys, galvanometer motors, sensors, reed switches, retention, and medical devices.
