% This is the magnetization curve shown in Figure 
% P9-2.  The first column is the field current in
% amps, and the second column is the open-circuit
% terminal voltage in volts at a speed of 1200 
% r/min.  The data will be loaded into an N x 2 array 
% named p92, with the first column containing If and 
% the second column containing the open-circuit voltage.
% MATLAB function "interp1" can be used to recover
% a value from this curve.
