In modern science and technology and industrial fields, magnetic holders are increasingly used. From simple desktop ornaments to complex mechanical systems, magnetic holders play a vital role. The core lies in its unique magnetic force maintenance mechanism, which mainly depends on the stability of the magnetic material itself and the effect of the magnetic field.

1. Stable magnetic moment arrangement of permanent magnets
Permanent magnets are a common magnetic material in magnetic holders. The magnetic moment arrangement of this type of magnet is highly ordered, forming a stable magnetic field. This stable magnetic moment arrangement enables permanent magnets to maintain their magnetic force for a long time without external energy input. Therefore, magnetic holders using permanent magnets have a long-lasting and stable adsorption force, which is very suitable for scenes where objects need to be fixed for a long time.

2. Controllable magnetic field of electromagnetic magnets
Unlike permanent magnets, the magnetic field strength and direction of electromagnetic magnets can be achieved by controlling the current. This controllability gives electromagnetic magnets greater flexibility and application prospects in magnetic holders. By adjusting the magnitude and direction of the current, the magnetic field strength and direction of the electromagnetic magnet can be precisely controlled, thereby achieving precise adsorption and positioning of objects.

The magnetic force maintenance mechanism of electromagnetic magnets lies in the stability of their current. As long as the current remains stable, the electromagnetic magnet can continuously generate and maintain the magnetic field, thereby maintaining the adsorption force on the object. This mechanism makes the electromagnetic magnet perform well in situations where the adsorption force or position needs to be frequently changed.

3. Application and Challenges of magnetic holders
The wide application of magnetic holders lies not only in their unique magnetic force maintenance mechanism, but also in their strong adaptability and easy installation. However, with the continuous expansion of application scenarios, magnetic holders also face some challenges. For example, how to ensure the stability and reliability of magnetic holders in extreme environments, how to further improve the adsorption force and accuracy of magnetic holders, etc.

In order to meet these challenges, researchers are constantly exploring new magnetic materials and magnetic field control technologies. By improving the performance of magnetic materials and optimizing magnetic field control algorithms, the performance and stability of magnetic holders can be further improved to meet a wider range of application needs.

The magnetic force maintenance mechanism of magnetic holders mainly depends on the stability of the magnetic material itself and the effect of the magnetic field. Permanent magnets achieve long-lasting and stable magnetic force with their stable magnetic moment arrangement, while electromagnetic magnets achieve controllable magnetic field strength and direction by controlling current. The application of these two magnetic materials in magnetic holders has its own characteristics, providing strong support for the development of modern science and technology and industrial fields.
