FaQ about Magnets and Services

In this section we have grouped together all the most frequently asked questions. You can also read our in-depth articles related to specific topics.


This is a tough question, since the determining factor is the intended role of the magnet. Ferrite magnets, although weaker, are surely cheaper, while neodymium magnets are stronger and therefore more expensive. Read More in a dedicated article

The best practice is to slide one over the other; we advise against trying to pull them apart vertically, since you may hurt yourself or damage the magnets.

We advise against such practice, since the Neodymium would make the Ferrite lose his magnetization, therefore becoming useless.

You can successfully use magnets on non-ferrous materials with the help of bioadhesive tape, glue or screws. You just put one magnet in place and use another of opposite polarity to make them safely stick together.

Oxidation, electric discharges and high temperatures (always follow our guidelines) are some of the main factors that can damage a magnet and cause a loss of magnetization. If you want to know more about that and learn how to properly store your magnets, you can read our complete guide: Loss of Magnetization and Demagnetization of Permanent Magnets


All these acronyms indicate the maximum temperature a magnet can withstand before permanently losing some of its magnetization. One of these letters can be placed after the grade of the magnet to indicate its resistance to demagnetization. An example for a magnet with an “M” resistance is N35M, generally means that a magnet can be used in an operating environment up to 100°C.  An “H” magnet performs ok up to 120C, “SH” up to 150C, “UH” up to 180C, “EH” up to 200C, and a “TH” up to 220C.  These are general specifications and other factors do play a role in coercivity decisions. 80 degrees Celsius is the standard limit (no acronym in the product page), but on request we are also able to produce magnets with higher heat resistance.

These attributes stand for the magnetization grade.

It tells the adhesive force of the magnet; the higher the number after the N, the stronger the force.

Yes they are. We always provide our customers with half and half polarities to guarantee that, no matter the final usage, the magnets can be made to stick together or against a metal surface without issues!

Yes, they do. The difference is so negligible, that we can safely say that the adhesive force is the same.
Magnetization is obtained through an electric discharge inside the magnetizer. The side from which the electricity enters the magnet becomes the north pole, the exit side becomes the south one.
We advise against cutting neodymium magnets. Being made by extrusion and of powders, they are very prone to damage; moreover, the magnetization could be lost. After you cut a magnet, the polarity will invert where the cut is made.

Neodymium magnets rust easily, therefore it is very risky to use them in humid environments if not adequately protected. The solution to this problem is to use plastic-encased magnets or resin-coated pot magnets. On the other end Ferrite Magnets are very resistant to corrosion, oxidation and humidity.

Among our coatings you can choose between zinc, nickel, gold, and black epoxy.
If the magnet has to come in contact with the skin, you would want to opt for a zinc-coated one. This guarantees that the magnet is nickel-free. Otherwise, the differences between the two coatings are just minor and cosmetic, the nickel being shinier and smoother.
Gold and black epoxy coatings offer a different color than the standard gray, but do not improve the grade of protection.

A marked magnet has a red or black dot on the relevant pole. This way the client knows the correct polarity and it becomes easier to assemble the magnets together (north against south).

Neodymium magnetic systems are specifically designed to maximize the adhesive force. Indeed, the strength of the assembled pot magnet is higher, thanks to the iron pot that redirects all the magnetic attraction towards the free side of the magnet.
Under usual circumstances, neodymium magnets lose 1% of their magnetism each year. If, on the other hand, they are exposed to higher than recommended temperatures (the standard in 80 degrees Celsius), or to electric discharges (galvanic bath), they can likely lose their magnetism altogether. In a theoretical scenario where 10 magnets undergo the same stress, it is not guaranteed that all of them will become unmagnetized, but is very likely that a good portion of them will.
Without a specific treatment, neodymium magnets can withstand a maximum temperature of 80 degrees Celsius. We are also able to produce magnets that reach 200 degrees. Please, send us a request to make sure that magnet size you are interested in is available with these custom treatments.
Our neodymium magnets come with axial magnetization as standard. On request we can provide different directions as well.

Axial magnetization means that the disc or ring is magnetized through its depth or height, and the poles are located on the flat surface. Diametrically magnetized means that the magnetic axis runs through the diameter, and the poles are located opposite along the lateral surface. Example of axial magnetized magnet:

The price of the required raw materials fluctuates rapidly, therefore the price of the magnets in our shop can change rapidly and considerably in a short amount of time according to the current market situation.


Ferrite magnets are made of two different iron alloys: with strontium or with barium.

Ferrite magnets are widely used in souvenirs and gadgets, magnet therapy and in the speaker manufactory.

It is a common misconception that ferrite magnets are cheaper than neodymium ones.
Having less adhesive force, in order to reach the same one as a neodymium magnet the ferrite magnet will have to be quite bigger, raising its cost.


Plastoferrite is a type of magnetized rubber band made of 90% barium- or strontium-ferrite and 10% of thermoplastic components.

Usually it is used as fridge gasket, as support for flyscreens, as advertisement billboards, as support for lightweight but cumbersome materials, for magnetic labels, as magnetic board or as magnet for gadgets and souvenirs.
