Consider a two-dimensional model and assume that horizontal magnetic field
H
τ
is polarized linearly at a clockwise angle
to the x-axis which runs along the model
strike. According to (4.4)

The tipper ratio has minimum

These relations can be readily extended to a three-dimensional model. We will
look for a
