Explanation with list magnetic / non-magnetic
Which substances, or rather elements, are magnetic and which are not magnetic? The term ferromagnetism is used to describe this. Ferromagnetism is the best known type of magnetism in a solid. It can be explained by the fact that the elementary magnets of the atoms of the material tend to align themselves in parallel. These either generate a permanent magnetic field themselves or are strongly attracted by a pole of an external magnetic field.
Now what is magnetic and what is not magnetic? Let's look at a list of them:
List of magnetic substances / elements:
- Iron (at room temperature)
- Cobalt (at room temperature)
- Nickel (at room temperature)
- Gadolinium (low temperature)
- Dysprosium (low temperature)
- Holmium (low temperature)
- Erbium (low temperature)
- Terbium (low temperature)
In addition, numerous alloys are ferromagnetic. Note: An alloy is a metallic material that consists of at least two elements. Together they must have the typical metal feature of the crystalline structure with a metal bond.
List of non-magnetic substances / elements:
- and much more
Examples of magnetic substances
In this area, examples of magnetic and non-magnetic substances will be presented.
Explain how the magnetic lines spread around magnets.
- Field lines run from the North Pole to the South Pole.
- No overlapping of the field lines.
- A stronger magnetic field is represented by a higher density of the field lines.
