Safety Information

This information sheet is delivered with every shipment as well. If you give away our magnets please submit this information sheet necessarily. Especially important if it is a present for children.

Is it possible to process, drill or saw the neodymium magnets up? 

Since the material is sintered the magnets can be difficult to process. This is due to the hardness and brittleness of its components.
By trying it wear gloves and safety glasses while handling. Only use special diamond tools and enough cooling water. The processing can produce dusts while drilling that can ignite or burn at high temperature.
When the magnet achieved the processing temperature of 80 ° it loses its magnetic property.
Once the coating is breached, the neodymium magnet is no longer protected against corrosion and oxidation. After a short time it begins to rust. We advise you to drill or cut off the magnets becuase they are then probably destroyed and they are no longer protected from rust because of the lack of coating.You can fix magnets to each other by using glue. 


Please pay attention to magnetic media (floppy disks, hard disks, USB drives, digital cameras, credit cards, audio and video cassettes), which could be erased or damaged from magnetic fields.
Magnets can destroy or influence electronic and mechanical components for example pacemakers, monitors, compasses, etc… Always observe the specification of the product manufacturer. You should keep a safety distance of 1 meter.

Does the magnetic force decrease?

The reduction of the magnetization is not measurable by human standards. It is established that magnets are not to use at temperatures higher than 80 °C. This is the maximum working temperature of neodymium magnets N40. The magnetic force can vanish even by beating the magnets with a hammer. Other opposing magnetic fields, chemical and radiation effects as well can cause the destruction of the magnets.

Is it possible to fix or stick the magnets with glue? 

Yes, to fix  or stick magnets for example onto wooden letters, we recommend our UHU plus endfest 300 2-Kompentenkleber (available at www.magnet-  Lastly the adhesion to plastic, plastic, marble, etc. is possible.

Can magnets chip or break? Breaking and chipping risk

Yes, because of the Neodymium’s preparation process (sintering). The material results brittle. Most often the magnets break because of collision. In particular, a collision between a disc magnet and a strong sphere magnet breaks in the rule the disc magnet. It is also possible that fragments disperse at such a collision. You should always wear gloves and safety glasses, especially by using larger magnets (KOLOSS - GIGANT).
In any case, you should always handle magnets with caution and avoid collisions.

Finishing / Coating:

Our magnets are usually coated with a thin nickel layer.  If you are allergic to nickel, we recommend not to come in touch with the magnets. With frequent use the layer vanishes. This usually occurs unintentionally at the contact points in a long time.
If required we can also supply magnets with zinc or gold coating. Our customer serice is at your service to help you.

Handling / Danger of wounds

Never let the magnets collide without control. This disperse magnet chips and they might wound the eyes.
The neodymium magnets are not to be confused with standard "fridge magnet". Especially larger magnets reveal enormous strength.  Danger in case of carelessness!
There is a risk of skin bruising! By using large magnets, always wear gloves. DO NOT test the magnets on body parts such as fingers, ears, nose ect.

Magnets and children

Keep our neodymium magnets out of reach of children under 3 years of age.
The small magnets can be easily swallowed and larger magnets can pinch and press some body parts. 

Please follow these instructions and enjoy using our magnets. 


The company magnets4you GmbH guarantees the functionality of the magnets and magnetic products delivered, the functionality is based mainly on the strength of attraction shown in the details of each product. The method for determining the force of attraction applied is shown on our website.
In the event that the following effects will appear on our products there is no possibility for the customer to make any claims regarding the quality of the magnets and to request for refund or exchange.

a) Neodymium magnets

• Coating exfoliation
When neodymium magnets collide violently with each other (in both cases when it is done on purpose or not) there is the possibility of the external coating to brake or flake.
The coating can also fade and become detached even in the case of a continuous handle.

• Metal and magnetic splinter
Because of misuse is possible that magnets break. This can happen when two magnets collide uncontrollably or when they fall down. A broken magnet as a result of these causes can not be replaced and therefore is not subject to warranty.

• Loss of magnetic force due to temperature
All our neodymium magnets can be used and exposed to a maximum temperature of 80 ° C. Exposure to higher temperatures could cause decrease or loss of its magnetic force.

b) Ferrite magnets

• Information regarding the surface of ferrite magnets
Ferrite magnets are produced through a sintering process. The magnets may have small recesses or of having sharp edges due to the manufacturing process and this is not to be considered as product defect.

• Loss of magnetic force due to temperature
All ferrite magnets of our range can be used and exposed to a maximum temperature of 250 ° C. Exposure to higher temperatures could cause a decrease or loss of the magnetic force.

• Loss of magnetic force due to the use with a stronger magnet
Ferrite magnets may change their magnetic field or lose their magnetic force if put in contact with neodymium magnets because of their high magnetic field power.
It is better to keep the magnets separated with a minimum distance of 3 cm.

The warranty lasts for two years from the time of shipment. The buyer is obliged to monitor and report immediately any defects or errors that may occur during production under paragraphs 377 and § 378 HGB according to the law in force in the Federal Republic of Germany. It does not include the transfer of warranty claims to third parties.
