GEOLOGY

Detailed explanation-1: -Ferromagnetic materials like iron and cobalt, has very large magnetic susceptibility that is positive susceptibility, unlike diamagnetic material which has negative susceptibility.

Detailed explanation-2: -Hint: Susceptibility of a material is defined as the ratio of the magnetization of the material to the field intensity. Ferromagnetic materials are substances that get strongly magnetized when placed in an external field. This suggests that they have large positive values for susceptibility.

Detailed explanation-3: -magnetic susceptibility of ferromagnetic materials is in the range of 1000-10000. Iron, cobalt etc are ferromagnetic in nature.

Detailed explanation-4: -Ferromagnetic materials such as iron, steel etc. have magnetic susceptibility >10, 000.

Detailed explanation-5: -Magnetic susceptibility of ferromagnetic substance is positive in nature and it’s magnitude is very very greater than 1.
