14. What are paramagnetism and ferromagnetism?
What type of substances would make better permanent magnets- ferromagnetic or ferrimagnetic?
Answers
Explanation:
What type of substances would make better permanent magnets, ferro. Solution : Ferromagnetic substances make better permanent magnets. This is because the metal ions of a ferromagnetic substance are grouped into small regions called "domains". Each domain acts as a tiny magn
=Diamagnetism refers to materials that are not affected by a magnetic field. Paramagnetism refers to materials like aluminum or platinum which become magnetized in a magnetic field but their magnetism disappears when the field is removed.
=Ferromagnetism refers to materials (such as iron and nickel) that can retain their magnetic properties when the magnetic field is removed. Ferro is the Latin word for iron (this is the reason behind the atomic symbol of iron- Fe), a material which displays strong magnetic properties.
