Safety information on ferrite magnets

Read this before you buy ferrite magnets!

Magnets pose a danger to children

Children are often drawn to magnets, especially colourful ones. Sometimes they even resemble real food or candy, increasing the risk of children putting magnets in their mouths and swallowing them. Swallowing multiple magnets at once can cause them to stick together in the digestive system, causing significant harm to the body. Remember: magnets are not toys! Ensure that small children do not play with magnets.

Magnets and electronic equipment

Magnets should always be kept a safe distance from electronic devices like pacemakers, hearing aids, and mobile devices. Ferrite magnets are not as strong and are unlikely to damage the equipment, while neodymium magnets are very powerful and pose a risk to it. To be safe, we recommend keeping both types of magnets away from electronic devices.

Not suitable for clothing

They have a somewhat dull dark grey colour and can rub off when something is rubbed against them. Therefore, ferrite magnets are not suitable for clothing, such as name tags.

Coating and texture

Ferrite magnets do not have a coating. The surface is uneven, and the edges may be bulged. However, the uneven edges do not affect the magnets' carrying capacity.

Ferrite magnets vs. neodymium magnets

Many neodymium magnets are strong enough to demagnetize or even change the poles of ferrite magnets. Therefore, always store ferrite and neodymium separately – at least 22 mm apart.


Magnets should always be securely packed before transportation. Ferrite magnets have relatively weak magnetic fields and are easy to shield. More effort is needed to protect neodymium magnets during transport.

Ferrite and neodymium magnets should always be transported at a minimum distance of 22 mm from each other (though 30 mm is recommended). If the distance is not maintained, it could happen that the neodymium magnets demagnetize or even swap the poles of the ferrite magnets.


Ferrite magnets can break if subjected to continuous pressure. If magnets break and shatter, they can injure people nearby.

Loss of magnetism

Neither ferrite nor neodymium magnets lose their magnetism on their own. They only become demagnetized if exposed to external factors like intense heat or strong magnetic fields.

Size deviations

The height varies in size by +/- 0.1 mm. The width and length, however, can vary by up to 2%, but at least 0.1 mm.


Ferrite magnets can be used at temperatures between -40 and 250 degrees Celsius (for comparison, most neodymium magnets lose their magnetism at temperatures above +80 degrees Celsius).

Outdoor use

Ferrite magnets are resistant to rust and therefore suitable for outdoor use.
