Metal magnetic hooks

Is there a significant difference in the ability of metal magnetic hooks to stick to vertical and horizontal surfaces?
There is indeed a significant difference in the adsorption capacity of metal magnetic hooks on vertical and horizontal surfaces. This is mainly related to the vertical and horizontal pull characteristics of the magnet.
The vertical pull of a magnet refers to the attraction or pull of the magnet in the vertical direction, while the horizontal pull is the attraction of the magnet in the horizontal direction. In the absence of external forces, the maximum vertical pull of a magnet is often greater than the maximum horizontal pull because gravity enhances the vertical pull. Therefore, under the same conditions, the adsorption capacity of metal magnetic hooks on vertical surfaces is usually stronger.
In addition, the vertical pull of a magnet is more dependent on the magnetic properties of the magnet itself, while the horizontal pull is related to the magnetic circuit design in addition to the magnetic properties. This means that when designing metal magnetic hooks, special attention should be paid to the design and optimization of the magnetic circuit in order to ensure its stable adsorption on different surfaces.
Metal magnetic hooks have a stronger adsorption capacity on vertical surfaces because they can make full use of the vertical pull characteristics of the magnet while avoiding possible resistance or instability in the horizontal direction. On horizontal surfaces, due to the limitation of horizontal pull and possible friction, the adsorption capacity of metal magnetic hooks is relatively weak.
If the magnetic force of a metal magnetic hook weakens or loses, is there any way to restore or enhance its magnetic force?
When the magnetic force of the metal magnetic hook weakens or loses its magnetic force, you can try the following methods to restore or enhance its magnetic force:
Remagnetization: Remagnetization is a common method to restore magnetism. You can use a stronger magnet and place the same poles of the two facing each other for a period of time to re-magnetize the metal magnetic hook. This method is simple and direct, but the effect may vary depending on the hook material and magnetization conditions.
Coil method: If conditions permit, you can try to use the coil method to restore magnetism. The specific steps are: insert the metal magnetic hook into a energized coil and magnetize the hook through the magnetic field generated by the current. This method requires certain electrical knowledge and skills, and you need to pay attention to the current strength and time to avoid damage to the magnet.
Clean the surface: Make sure the surface of the metal magnetic hook is clean and dust-free, as dirt, grease or other impurities may affect its magnetic force. Use an appropriate cleaner (such as alcohol or mild detergent) and a soft cloth for cleaning.
Check the installation surface: The cleanliness, flatness and material of the installation surface will also affect the adsorption effect of the magnetic hook. Make sure the installation surface is free of impurities, oil, and is compatible with the material of the hook.
Avoid high temperatures and severe vibrations: High temperatures and severe vibrations may cause the magnetism of metal magnetic hooks to weaken. Therefore, try to avoid exposing the hook to high temperatures or severe vibrations.
Replacing the magnet: If none of the above methods can restore or enhance the magnetism, you may need to consider replacing the magnet. Purchase a magnet that matches the original hook and replace it according to the instructions.
