I would like to plot the magnetic field around a magnet. I have trying to plot magnetic field potential, and been partially successful for a point source, I believe. But would like to know if it is ok, and how can I make it better with bigger dimension. If you could correct me or give me suggestions, that would be great. Thank you.
%%2D plot practice
xa = linspace(-1,1,50); % x-axis or all positions in X
ya = linspace (-1,1,25);
[Y,X] = meshgrid(ya,xa);
D= X.^2 +Y.^2;
k= 1e-7; % mu/4*pi
m= 1e-4; %magnetic moment
M_pot= (k*m)./D; % Magnetic potential
% imagesc(xa,ya,D');
pcolor(xa,ya,M_pot');
shading interp
% smoothens the pixel boxes. with pcolor.

IT's been very long we studied about it...why don't you give it's formula..so that users can see it and check whether code needs modification...
