Plot of Magnetization Vs Magnetic Field

13 views (last 30 days)
Dear Matlab Users, Hi to All, I have tried to plot the magnetization Vs Magnetic field. when the magnetic field is reduced the magnetization starts to randomize and also tends to go to zero but do not go to zero exactly for which probability is also used. For every value of B there is value of magnetization.
The graph should be between magnetic field and magnetization( In my graph i am getting one point only)
THANKING YOU ALL IN ANTICIPATION

You set:
B = 2;% Tesla Initial Magnetic Field
early in your code, and then you iterate this loop:
for i = 1 : length(B)
precisely once as the result, so that:
magnetization_new(i) = magnetization * cosd(theta_new);
is calculated only once, and:
plot(B,magnetization_new,'-*')
plots the one point you told it to plot.
I removed the subscript from ‘magnetization_new’ in the plot call because when you re-write your code and get vectors for ‘magnetization_new’ and ‘B’, that will throw an error because you will be plotting the vector of ‘B’ against only the last element of ‘magnetization_new’.
Beyond that, I don’t know what you’re doing so I can’t suggest a way to fix your code.
