write a short note on ferrromagnetic materials...!
Answers
Answer:
Ferromagnetic materials are those materials which exhibit a spontaneous net magnetization at the atomic level, even in the absence of an external magnetic field. When placed in an external magnetic field, ferromagnetic materials are strongly magnetized in the direction of the field.

Answer:
Explanation:
Ferromagnetic materials are those materials which exhibit a spontaneous net magnetization at the atomic level, even in the absence of an external magnetic field.
Ferromagnetism gets its name from the word ‘ferrous’ which means iron which was the first metal known to show attractive properties to magnetic fields.
Ferromagnetism is a unique magnetic behaviour that is exhibited by certain materials such as iron, cobalt, alloys, etc.
It is a phenomenon where these materials attain permanent magnetism or they acquire attractive powers.
