  The propagation of the effects connected with the occurrence of magnetization
reversals in an amorphous ribbon of Fe$_{63}$B$_{64}$Si$_{8}$Ni$_{15}$ has been
investigated using a method based on two pickup coils separated by a distance
variable between 2 an 40 mm. The ratio $R$ between the voltage signals induced
in the coils contains information on the location where the magnetization
reversal took place. This information can be extracted by knowing the function
$V(x)$ which represents the attenuation of a signal generated by a reversal
that took place at a distance x from the coil. A mathematical model for
extracting this function starting from the histogram of the experimentally
measured values of $R$ is presented. The attenuation function obtained in this
way is relatively independent on the distance between the coils, and this is in
strong support of the correctness of the model adopted.
