Maybe you have heard about magnetite but you don’t really know what it is and its relationship with magnets. Below, we give you all the keys you should know about this material.
What is known as magnetite
Well, when talking about magnetite we mean a very dense mineral, 5.8 gr/cc, which, however, is fragile, moderately hard and has ferromagnetic properties, such that it is capable of attracting iron. and other metals. It has a brownish black color, has a metallic shine and a black footprint. Its main characteristic is its strong magnetism, in addition to its aforementioned black color and the hardness it presents. Precisely because of its strong magnetism, due to a phenomenon of ferrimagnetism, this mineral is a magnet.
Origin of magnetite
Regarding the origin of this mineral, it appears in fragments of ancient metamorphic rocks. The largest deposits of magnetite that can be found in the world are considered to be in northern Sweden, Chile, Norway, Romania, Siberia, as well as in the Bushveld igneous complex. In Spain, the amount that can be found in areas such as Toledo and León stands out.
Types of magnets
As we say, magnetite is a type of mineral that, due to its strong magnetism, is a magnet. Precisely if we talk about magnets we see that different types can be found. Highlighting the following.
Neodymium magnets
Neodymium magnets are the most powerful type of magnet that can be found and among their properties are those of holding a magnetic glass board. They are ultra-strong magnets that make it possible to hold stacks of papers or hang knives and tools on the wall thanks to their power. Therefore, they are powerful magnets.
Therefore, neodymium magnets are characterized by offering high magnetic adhesion, making them perfect for use in large areas or interior surfaces. They are a type of magnet that loses its magnetic strength in environments over 80ºC.
Ferrite magnets
On the other hand, we find the so-called ferrite magnets. This type of magnets are characterized by being options that in themselves are made of a resistant material, difficult to dismantle and with a great magnetic capacity. They are recommended for use outdoors, and can withstand temperatures of up to 250º without losing their magnetic properties. They are magnets resistant to corrosion and have a very economical price.
Magnetically Charged Vinyl Magnets
When talking about magnetically charged vinyl magnets, reference is made to a magnetizing process on the face of a vinyl. In this way, with the magnetic sheet you have a magnet and on the other side you can write, print or cover it with different materials. This means that the magnetic vinyl has maximum customization capacity, being able to make a magnet of practically any design that is reflected on this type of surface.
To do this, for example, you can resort to the use of adhesive magnets precuts that will help you personalize your design if you are doing modeling. In this sense, just take a look at all the options that are available to you to see that you can find models of different sizes, shapes and formats, so that they adapt to all types of modeling needs and projects.
Other aspects to take into account
Now that you know the types of magnets that you can mainly find on the market and what mineral they are mainly made of, it is important that you know that they are a perfect option to use in modeling. That is, to use in the making of scale models, models or figures. To carry out this type of work, in addition to choosing the most appropriate type of magnet, you must take into account another series of aspects such as also selecting the modeling glue suitable among the extensive offer that you can find on the market.
In any case, a design must be made in advance to make it clear what the model or scale figure to be designed will be like and thus be able to begin to see how it will actually be carried out and materialized. With planning and the right materials, including magnets, carrying out a modeling project will be a feasible and successful task.
