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:

  • copper
  • aluminum
  • lead
  • gold
  • silver
  • magnesium
  • Wood
  • plastic
  • paper
  • and much more

Examples of magnetic substances

In this area, examples of magnetic and non-magnetic substances will be presented.

example 1:

Explain how the magnetic lines spread around magnets.

Solution:

  1. Field lines run from the North Pole to the South Pole.
  2. No overlapping of the field lines.
  3. A stronger magnetic field is represented by a higher density of the field lines.
