Which material does the magnetic force of Pot Magnet With Ring-Pull mainly come from?

The magnetic force of Pot Magnet With Ring-Pull mainly comes from the high-performance magnetic materials used inside them. The magnetic strength of Pot Magnet With Ring-Pull depends on neodymium iron boron (NdFeB) magnets. Common magnetic materials include:

Neodymium iron boron (NdFeB) magnets
This is one of the strongest permanent magnetic materials on the market and belongs to the third generation of rare earth permanent magnets. It has extremely high magnetic energy product and coercive force, and is suitable for occasions requiring high magnetic force. However, it is sensitive to temperature and its performance will decrease at high temperatures.

Ferrite magnets
It has low cost and moderate magnetic properties, and is suitable for general use. It is usually used for medium and low intensity magnetic adsorption needs, such as home decoration, advertising display, etc. It has good temperature tolerance and is suitable for long-term use.

Samarium cobalt (SmCo) magnets
It has stable magnetic properties and high temperature resistance, and is suitable for applications in extreme environments. However, it is expensive and is usually used in special industries or aerospace fields.

Other materials
Such as aluminum nickel cobalt (AlNiCo) magnets, which have weak magnetic properties but good thermal stability and mechanical properties.

What specific application scenarios are pot-shaped magnets with pull rings suitable for?
Pot-shaped magnets with pull rings are widely used in many fields due to their unique structural design and good magnetic properties, including:

1. Industrial field
Tool fixing: used to fix wrenches, screwdrivers and other tools in factories and workshops to improve work efficiency.
Clamps and clamping devices: used to clamp metal parts, such as fixing workpieces on assembly lines.
Logo and sign fixing: used to fix safety signs, operating instructions, etc. in the workshop.
Automation equipment: used for magnetic levitation systems, magnetic drive devices, etc.

2. Commercial and display fields
Window decoration: used to fix goods or decorations on display racks.
Advertising display: used to fix posters, display boards, light boxes, etc., for easy replacement and maintenance.
False ceiling clips: used to fix decorative false ceilings for easy installation and removal.
Light stand fixing: used to fix lamps for easy installation and adjustment.

3. Home and Lifestyle
Festival decorations: such as Christmas wreaths and holiday decorations.
Office supplies: used to fix notes, labels, documents, etc.
DIY projects: used for magnetic toys, magnetic refrigerator magnets, magnetic picture frames, etc.
Kitchen applications: used to fix metal objects such as knives and pots for easy access.

4. Special uses
Torque limiting seals: used in mechanical sealing devices to prevent excessive torque from damaging the equipment.
Magnetic adsorption devices: used in medical equipment, laboratory equipment and other occasions that require precise control.

What factors affect the tensile strength of pot magnets?
The tensile strength of pot magnets (i.e. the maximum weight or pressure it can adsorb) is affected by many factors, which together determine the actual use effect of the magnet. The following are the main influencing factors:

1. Magnet material
NdFeB magnets: the strongest magnetic force, but the price is higher.
Ferrite magnets: moderate magnetic force and low cost.
Samarium cobalt magnets: stable magnetic force and high temperature resistance.
Different materials have different magnetic properties, which directly affect the pulling force of the magnet.

2. Magnet size and shape
The larger the size: the larger the surface area of the magnet, the larger the contact area with the adsorbed object, thus increasing the pulling force.
Shape effect: The curved surface design of the pot-shaped magnet helps to evenly distribute the magnetic field and improve the adsorption stability.

3. Air gap (Gap)
The smaller the air gap: the smaller the distance between the magnet and the adsorbed object, the higher the magnetic field strength, and the greater the pulling force.
The larger the air gap: the magnetic field weakens and the pulling force decreases.

4. Material and surface condition of the adsorbed object
Material: Ferromagnetic materials (such as steel, iron, nickel, and cobalt) respond better to magnetic force.
Surface flatness: The flatter the surface, the closer the contact between the magnet and the object, and the greater the pulling force.
Coating or non-metallic layer: Non-magnetic materials such as plastics and paints will hinder the penetration of the magnetic field and reduce the pulling force.

5. Temperature
High temperature effect: Magnets will lose some of their magnetism at high temperatures, resulting in a decrease in pulling force.
NdFeB magnets: will be significantly demagnetized above 80°C.

Ferrite magnets: have good temperature resistance and can usually withstand temperatures around 120°C.

6. Magnet arrangement
Single magnet: relatively small pulling force.
Combination of multiple magnets: through reasonable arrangement, the overall pulling force can be enhanced, but attention should be paid to the direction and polarity.

7. Installation method
Vertical installation: magnets are usually adsorbed in the vertical direction, and the pulling force performance is better.
Horizontal installation: when adsorbed in the horizontal direction, the pulling force will decrease due to gravity.
