1. Magnetometer measurement:
Using a magnetometer is a primary method for directly measuring the magnetic field strength of a round magnet. A magnetometer measures the magnitude of magnetic force by sensing a magnetic field and converting it into an electrical signal. During measurement, the magnetometer is placed at a certain distance from the surface of the magnet, usually in the range of a few millimeters to a few centimeters. This method is particularly effective for magnets of standard shapes and sizes because the accuracy and repeatability of the measurement can be ensured through calibration and standardized procedures. Magnetometer measurement not only provides a numerical value of the magnetic field strength, but also helps to evaluate the distribution and directionality of the magnetic field, which is particularly important for some applications.

2. Adsorption force measurement:
Adsorption force measurement is a method for indirectly evaluating the magnetic strength of a round magnet. It is performed by measuring the adsorption force between a magnet and another magnetic material (such as an iron block or another magnet). During the experiment, a standardized force is usually applied to separate the two objects, and then the magnitude of the applied force is measured. This method requires precise force measuring instruments and standardized experimental procedures to ensure the accuracy and comparability of the measurement. Adsorption force measurement is generally applicable to scenarios where it is necessary to understand the adsorption and retention force of a round magnet in actual applications, such as various magnetic connections and clamping devices.

3. Magnetic flux density measurement:
Magnetic flux density is another important indicator to describe the strength of the magnetic field. It indicates the magnetic flux passing through a unit area. Using a magnetic flux density measuring instrument, the magnetic field strength generated by the round magnet at a specific location can be directly measured, which is particularly important for applications that require a detailed understanding of the magnetic field distribution and the direction of the magnetic lines of force. This method is generally suitable for precision measurements in scientific research and specific industrial applications, and can provide a more detailed and in-depth analysis of magnetic capabilities.

4. Magnetic force calculation model:
For complex round magnet structures or specific applications that require prediction of magnetic force strength, magnetic force calculation models can be used for numerical simulation and analysis. These models are based on physical equations and mathematical models, taking into account the geometry of the magnet, material properties, and surrounding environmental conditions, and estimate the magnetic force strength of the round magnet under different conditions through calculation. The magnetic force calculation model can provide an important reference for the design process, help optimize the performance and efficiency of the magnet, and ensure that it can meet the expected magnetic force requirements in practical applications.

5. Standardized testing:
For some applications, it may be necessary to meet specific international or industry standards to evaluate the magnetic force strength of the round magnet. These standardized tests include the use of standardized test equipment and procedures to ensure the accuracy and comparability of the measurement results. By complying with standardized tests, it is possible to verify that the round magnet meets specific performance indicators and requirements, while providing important support for product quality control.
