Diamagnetism vs. Ferromagnetism
Main DifferenceThe main difference between Diamagnetism, and Ferromagnetism is that Diamagnetism produces in resistance to the external magnetic field and goes when the external field is removed, whereas Ferromagnetism occurs in the direction of an external magnetic field and can continue to exist when the external magnetic field is removed.
Difference Between Diamagnetism and Ferromagnetism
Diamagnetism vs. Ferromagnetism
The materials which are not attracted by external magnetic fields are diamagnetic, whereas the materials which are strongly attracted by external magnetic fields are ferromagnetic.
Diamagnetism vs. Ferromagnetism
Each atom of diamagnetic materials has a net magnetic moment; on the other hand, each atom of ferromagnetic materials have their magnetic moment.
Diamagnetism vs. Ferromagnetism
The magnetization of diamagnetic materials when the external magnetic field is removed; on the other hand, the material of ferromagnetism can keep their magnetization when the external magnetic field is removed.
Diamagnetism vs. Ferromagnetism
The materials of diamagnetism can be easily separated from other materials because they have repulsions to magnetic fields; on the other hand, the materials of ferromagnetism can be separated by using low-intensity magnetic separators.
Diamagnetism vs. Ferromagnetism
The diamagnetic materials have no unpaired electrons, while ferromagnetic materials consist of many unpaired electrons.
Diamagnetismnoun
(physics) a weak form of magnetism that is only observed in the presence of an external magnetic field; due to an induced magnetic field in an opposite direction
Ferromagnetismnoun
(physics) The phenomenon whereby certain substances can become permanent magnets when subjected to a magnetic field.
Diamagnetismnoun
phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a magnet
Ferromagnetismnoun
phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed

Diamagnetism vs. Ferromagnetism
In the diamagnetism, the diamagnetic materials consist of single atoms which do not have a net magnetic moment; on the other hand, in ferromagnetism, the ferromagnetic materials consist of atoms which also have their magnetic moment.
Diamagnetic materials in diamagnetism bring into line their magnetic fields in the opposite direction to the external magnetic fields; on the flip side, ferromagnetic materials in ferromagnetism make parallel their magnetic fields in the equivalent direction as in the direction of external magnetic fields.
Diamagnetic materials misplace their magnetization in diamagnetism when the external magnetic field is removed; on the other hand, ferromagnetic materials can maintain their magnetization even when the external magnetic field is removed.
The diamagnetic materials do not get attracted to external magnetic fields, while ferromagnetic materials strongly get attracted to external magnetic fields. The diamagnetic materials have no unpaired electrons in atoms or ions; on the other hand, in ferromagnetic materials, it has many unpaired electrons in the atoms or ions.
The diamagnetic materials can easily be separated from many other materials since they consist of repulsions to magnetic fields, while ferromagnetic materials can be separated by using low-intensity magnetic separators.
What is Diamagnetism?
Diamagnetism is considered as the weakest magnet of all the three types of magnetism. All materials on earth are diamagnetic. The diamagnetic materials do not have a magnetic attraction towards other materials.
In the materials of diamagnetism, the magnetic moments of each of the separate electrons in the specific material are canceled out. Whenever a diamagnetic material is put under an external magnetic field, the material forms a specific magnetic field that competes with the external magnetic field, and as a result, the diamagnetic materials get repelled by the external magnetic field.
What is Ferromagnetism?
The ferromagnetic materials of ferromagnetism have unpaired electrons present in their atoms, so each atom has a clear magnetic moment. The magnetic moments of adjacent atoms incline to become associated and creating different regions in the materials known as domains. Though, many different domains may have their magnetic moments directing in different directions.
Whenever a ferromagnetic material is generally placed inside an external magnetic field, the many different domains present inside the magnetic fields become all align with the external magnetic fields. Some ferromagnetic materials are cobalt, nickel, iron, and their alloys.
ConclusionThe above discussion concludes that the diamagnetism, and ferromagnetism have differences, and the main difference between these is that the diamagnetism of some materials do not have a magnetic attraction, whereas ferromagnetism of some materials has a strong magnetic attraction.
