an attractive or repulsive field. Objects that get attracted by a magnet are called magnetic materials.<\/p>\n

Again, not all materials are naturally magnetic. There are certain types of material that require special modifications. At the same time, there are some that are non-magnetic materials.<\/p>\n

Here are some common magnetic materials:<\/p>\n

Types of Magnetism<\/h2>\n

1. Paramagnetism<\/h3>\n

Paramagnetism is a form of magnetism that is feebly attracted to an externally created magnetic field. Such kind of magnetism can only be exhibited by paramagnetic materials. Paramagnetic materials<\/a> are made of permanent atomic dipoles running parallelly in the same direction as the external field.<\/p>\n

When the external magnetic field is removed, paramagnetic materials lose their magnetic properties. However, the unpaired electrons will still exist. Due to their low positive susceptibility, paramagnetic materials are attracted by other magnets but they cannot attract other paramagnet materials.<\/p>\n

Another characteristic of paramagnetism is that it is temperature-sensitive. An increase in temperature decreases the magnetic moments of its atoms.<\/p>\n

You can only tell if a magnetic material is paramagnetic or not by looking at its electronic configuration. A paramagnetic material has unpaired electrons (an odd number of electrons). Some examples of materials that exhibit paramagnetism include titanium, oxygen, aluminum, etc.<\/p>\n

2. Ferromagnetism<\/h3>\n

Ferromagnetism<\/a> is a form of magnetism in which the magnetic material attracts or is attracted strongly by other magnetic materials. A ferromagnetic material gets magnetized when exposed to an external magnetic field. In stronger magnetic fields, ferromagnetic materials can be magnetized to the saturation limit.<\/p>\n

Removal of an external magnetic field does not take away their ferromagnetic properties. Ferromagnetic materials are also sensitive to temperatures beyond their curie point. Past this point, they lose their magnetism. However, on cooling, they regain their magnetic properties.<\/p>\n

The number of atoms ions in a ferromagnetic material even creates a magnetic field from within the material. Therefore, ferromagnetic materials have lasting magnetic moments. Some examples of ferromagnetic materials include; cobalt, nickel, iron, and some of their alloys.<\/p>\n

3. Antiferromagnetism<\/h3>\n

Antiferromagnetism<\/a> is a form of magnetism in which the atoms within a material are arranged uniformly but moving in the opposite direction from the adjacent atoms. Antiferromagnetic materials have unique qualities that can be used in applications like data storage, sensors, and spintronics.<\/p>\n

When antiferromagnetic materials are exposed to temperatures below the Neel point, they lose their antiferromagnetic properties. They become paramagnetic materials.<\/p>\n

Some examples of antiferromagnetic materials include; iron oxide, manganese oxide, chromium, copper (II) oxide, and nickel (II) oxide.<\/p>\n

4. Ferrimagnetism<\/a><\/h3>\n

There are magnetic material with:<\/p>\n

    \n
  • Can attract other magnets<\/li>\n
  • External magnetic fields can also attract these materials<\/li>\n<\/ul>\n

    Ideally, these are unique magnetic materials that experience both ferromagnetic properties and antiferromagnetic properties. Moreover, on exposure to extremely high temperature (above curie temperature), they will lose the external magnetic properties.<\/p>\n

    They regain their ferrimagnetism on cooling, making them permanently magnetic.<\/p>\n

    \"Ferrimagnetism
    Ferrimagnetism Overview<\/figcaption><\/figure>\n

    Generally, ferrimagnetism mainly occurs in ferrites (a type of magnetic oxide). Some examples of ferrimagnetic materials are yttrium iron garnet, trevorite, magnesioferrite, and magnetite.<\/p>\n

    5. Diamagnetism<\/h3>\n

    Diamagnetism is an occurrence in which some materials when exposed to an external magnetic field, tend to move away from the field. Naturally, all materials are diamagnetic. However, some materials have stronger magnetic properties that are stronger than their diamagnetic nature.<\/p>\n

    \"Diamagnetismo\"

    Diamagnetic materials don\u2019t exhibit any magnetic properties naturally, they only counter an external magnetic field by repelling it.<\/p>\n
