The ferromagnetic materials possess magnetic moment and thus magnetization even in the absence of the applied magnetic field, this magnetization is known as the spontaneous
In ferrimagnetic materials, the magnetic moments of unequal magnitude are aligned in opposite directions so that net magnetisation occurs. According to Neel, ferrimagnetism is the
Ferromagnetic materials can be classified as: Antiferromagnetic materials and Ferrimagnetic materials Reference: This article is referred from my book “electrical engineering materials” having ISBN 978-81-272-5069-0

When the specimen of a ferromagnetic material is magnetized by gradually increasing the magnetising fields, then the change of magnetic flux through the material is
