Some (undergraduate) text books like the "Atkins", "Barrett" or "Askeland" show simplified pictures to orientation polarization that are simply wrong. | |||
| |||
This figure reproduces roughly a picture from the (otherwise very good) "Askeland: The Science and Engineering of Materials". In the bottom part it is supposed to show water molecules without (left ) and with (right) an electrical field. | |||
Well - it is simply wrong. However, considering that this book only spends two pages on polarization mechanisms and dielectric constants, there simply is no room for the author to describe "details". | |||
The same is true for the magnetic equivalent of orientation polarization: paramagnetism. | |||
Here is a picture drawn after an illustration in the "Barrett" | |||
| |||
It is just as wrong as the picture above. However, the same "excuse" applies: This is Undergraduate stuff, much simplified, and without a discussion of the statistical nature of the orientation. | |||
