Manual magnet separators featuring a grip are used for various industrial applications, e.g. in separating materials, cleaning production lines, or recovering iron within waste. They function due to a strong magnetic zone, produced by ferrite magnets, placed in a shell containing a grip, which makes handling easier and improves accuracy in action.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from their strong power, neodymium magnets have these key benefits:

They do not lose their power approximately ten years – the reduction of strength is only ~1% (according to tests),
They show strong resistance to demagnetization from outside magnetic sources,
Because of the reflective layer of silver, the component looks aesthetically refined,
They have very high magnetic induction on the surface of the magnet,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
With the option for customized forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
Significant impact in modern technologies – they are utilized in HDDs, electric motors, diagnostic apparatus or even technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in compact dimensions, which allows for use in compact constructions

Disadvantages of neodymium magnets:

They may fracture when subjected to a strong impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time increases its overall robustness,
Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of rubber for outdoor use,
Limited ability to create precision features in the magnet – the use of a housing is recommended,
Potential hazard related to magnet particles may arise, especially if swallowed, which is crucial in the family environments. Furthermore, miniature parts from these products have the potential to complicate medical imaging after being swallowed,
Due to expensive raw materials, their cost is above average,

Handle with Care: Neodymium Magnets

Do not bring neodymium magnets close to GPS and smartphones.

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets are particularly fragile, which leads to shattering.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

If joining of neodymium magnets is not controlled, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them very firmly.

Do not give neodymium magnets to youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Safety rules!
