What does your textbook say about 5.6 MAGNETIC PROPERTIES OF MATERIALS?
The discussion in the previous section helps us to classify materials as diamagnetic, paramagnetic or ferromagnetic. In terms of the susceptibility χ , a material is diamagnetic if χ is negative, para- if χ is positive and small, and ferro- if χ is large and positive. A glance at Table . gives one a better feeling for these materials. Here ε is a small positive number introduced to quantify paramagnetic materials. Next, we describe these materials in some detail. TABLE . MAGNETIC SUSCEPTIBILITY OF SOME ELEMENTS AT K Diamagnetic substance χχ Paramagnetic substance χχ Bismuth
