What substances are magnetic?
There are different types of magnetic materials or magnetic substances, each with very different properties and very specific functions.
No doubt you tried that as a child and discovered that the magnet in the fridge does not stick everywhere. As it has been tried in vain to hang it on wooden windows and doors, always with the same result: the magnets are not fastened. Then we learned from the beginning that there are magnetic substances and non-magnetic substances.
Which have come to terms with this simple answer, others have looked closer and then perhaps wanted to know exactly what these magnetic substances are?
Now, some things have changed since we were kids, but not that much. For example, if you work in industry, manufacturing, aerospace or a similar sector, you are likely to be more interested in which materials are magnetic and which are not. This can be extremely important for specific designs, experiments and applications, and determine which materials to buy. So let's take a closer look:
What substances are found in magnetic materials?
There are different types of magnetism, such as electromagnetism or ferromagnetism, where the former, as its name indicates, is generated by the current and the latter by the atomic orientation of the material. Certain substances can be attracted by any type of magnetism, but for some magnetic materials, the temperature depends on whether it is magnetic or not. Actually, there are only 3 substances that are always magnetic:
- Iron (at room temperature)
- Cobalt (at room temperature)
- Nickel (at room temperature)
- Gadolinium (low temperature)
- Disprosio (low temperature)
- Holmium (low temperature)
- Erbio (low temperature)
- Terbium (low temperature)
There are also many ferromagnetic alloys. Alloys are metallic materials consisting of at least two elements, such as the alloy of super magnets made of neodymium, iron and boron.
Therefore, if you have application areas where you want to take advantage of magnets, you must first inform yourself thoroughly so that planning takes into account all the necessary material factors from the beginning. The application itself is crucial to what types of magnets and what format you need, as well as what magnetic materials you should use. In our assortment, we offer the most different types of magnets, from electromagnets on ferrite magnets to neodymium magnets. Of course, these can also be produced in a wide variety of shapes and sizes. Contact us for an individual and personal consultation, after which we can offer you the best solution for your needs.
