It is homogeneous and isotropic and if the electric field is not too great, the

electrical distortion that it produces in a molecule is

**proportional**to the field. Thussuch a medium is practically an ideal one in the sense of the preceding chapter,

If this restoring torque is

**proportional**to the displacement, the displacement is**proportional**to the product of the currents in the two coils and hence can be usedto measure various electrical quantities. Figure 9.20 is a schematic diagram of ...
