Q: Materials that can be magnetized are called?


Read this paragraph and choose the correct option from the provided answers:

In other materials, electrons fill the orbitals of the atoms that make up the material in a way to allow for each atom to have a tiny magnetic field, giving each atom a tiny north and south pole. There are large areas where the north and south poles of atoms are all lined up in the same direction. These areas are called magnetic domains . Generally, the magnetic domains point in different directions, so the material is still not magnetic. However, the material can be magnetized by placing it in a magnetic field. When this happens, all the magnetic domains become aligned, and the material becomes a magnet. This is illustrated in Figure below . Materials that can be magnetized are called ferromagnetic materials . They include iron, cobalt, and nickel.

 Choices:

- atoms materials

- iron materials

- inclusions materials

- ferromagnetic materials


A:
ferromagnetic materials
