To decide on the right type of magnet, you must know the purpose for which you need the magnet. In order not to experience unwanted surprises afterwards, it is advisable to define exactly what the magnet is used for, as there are also differences here. Therefore, one or the other model is more questionable, whether a magnet, for example, withstands high temperatures, or this factor is not necessarily relevant. The same goes for outdoor magnets, they are very different from those used in the office or at home.
It is worth knowing, therefore, that ferrite magnets are cost-effective and, on the other hand, withstand higher temperatures of up to 250 degrees. This type of magnet is recommended for exterior surfaces, but not so much for interior areas where aesthetics may be more important than magnetic strength. The advantage of neodymium magnets is their strong adhesion. Therefore, they are ideal when there are no large areas available, you need to save space and the magnet should contain several sheets at a time. These magnets usually have a coating that makes them easy to customize and adapt to the decoration of the room.
In comparison, a neodymium magnet of the same size as a ferrite magnet is stronger, so it is recommended in cases where space is limited. The neodymium magnet shows up to ten times stronger adhesion than the ferrite magnet. The latter, however, is cheaper, but also more stable in price, since rare earth elements are not used in its processing, which are subject to significant fluctuations in prices. In addition, ferrite magnets can be used at temperatures of -40 degrees to 250 degrees Celsius, while neodymium magnets lose their magnetic strength at more than 80 degrees.
Another interesting difference is that ferrite is corrosion resistant to chemicals and suitable for outdoor use, but neodymium is not. Neodymium breaks easily, while ferrite is much stronger and difficult to dismantle. Both magnets retain their magnetic strength over time, and there is no reason to fear that they will naturally lose it. However, ferrite magnets can be demagnetized by the influence of stronger neodymium magnets. This process can also reverse your poles.
As we have already indicated, the ferrites are not coated and have a grey colour. Therefore, they are not so easy to decorate and adapt to the interior design. The neodymium ones have a silvery colour due to their nickel and copper based coating and combine perfectly with the decoration. Magnets near devices such as pacemakers or hearing aids can affect their function. If there is a risk of magnets approaching such devices, we recommend using ferrit
