I'm trying to plot a graph inside a loop for, because i have to increase g value then calculate L(inductance):

N=35;
Ac = 9*10^-4;
Ag=Ac;
lc = 30*10^-2;
ur = 70000;
u0 = 4*pi*10^-7;
x=0.0001:0.00001:0.001;
for g=0.0001:0.00001:0.001
       
    Rc = (lc)/(ur*u0*Ac);
    Rg = g/(u0*Ag);
    Rtot = Rc+Rg;
    
    L= N^2/Rtot;
    plot(x,L,'-','LineWidth',2);
    pause(.2)
end

But the popout of the plot show but nothing happen, can someone fix the code?

But L doesn't have any dependence at all on x, so what's the point in having it?

Maybe you're looking for

N=35;
Ac = 9*10^-4;
Ag=Ac;
lc = 30*10^-2;
ur = 70000;
u0 = 4*pi*10^-7;
Rc = (lc)/(ur*u0*Ac);
g=0.0001:0.00001:0.001;
Rg = g/(u0*Ag);
Rtot = Rc+Rg;
L= N^2/Rtot;
plot(g,L,'-','LineWidth',2);

???

It seems like you want the drawing to be animated because you used pause(0.2) so try it this way:

clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables. Or clearvars if you want.
workspace;  % Make sure the workspace panel is showing.
format short g;
format compact;
fontSize = 16;
N=35;
Ac = 9*10^-4;
Ag=Ac;
lc = 30*10^-2;
ur = 70000;
u0 = 4*pi*10^-7;
x=0.0001:0.00001:0.001;
allg=0.0001:0.00001:0.001
% Animate the curve drawing.
for k = 1 : length(allg)
    g(k) = allg(k);
    Rc = (lc) / (ur*u0*Ac);
    Rg = g(k) / (u0*Ag);
    Rtot = Rc+Rg;	
    
    L(k) = N^2 / Rtot;
    plot(x(1:k), L(1 : k),'b.-','LineWidth',2, 'MarkerSize', 17);
    grid on;
    title('L vs. x', 'FontSize', fontSize);
    xlabel('x', 'FontSize', fontSize);
    ylabel('L', 'FontSize', fontSize);
    pause(.2)
end
g = gcf;
g.WindowState = 'maximized';
