Question

can you please write this code in different way because this is for my friend and i want to change it to submit it other wise we both will get zero

i attached also the question down also i am not sure of his answers so just try to solve it and your trial will be so apprciated anyway thanks for your time and efforgts :-

the question was

From Maxwell's equations we have, 0B From this expression, we need to compute H, we have the relation between B and H as B urt MATLAB code is given below for computing H. clc; clear all; close all; % from maxwell's equations we have del X E--Del B / Delt % from the abve expression we need to obtain H.

Write a MATLAB script that finds the symbolic expression of H from E given Cartesian coordinates as, E-E,(x, y, z, t) , + Ey(x, y, z, tay + Ez(x, y, z, t) ,

Answer 1

Matlab code:

% aim: to find the H; we have B=UH; { U is permeability }
% H=B/U;
%maxweell's equation--> del*E=-{del(B)/(del(t))}
% E is electric field intensity
% B magnetic flux density.

clc;clear all;close all;
  syms x y z t;
U=4*pi*10^(-7) % pearmiabilty
Ex=x^3*y^2*z;
Ey=x*y^3*z^2;
Ez=x^2*y*z^3;
E=[Ex,Ey,Ez] % Electric field
X=[x y z];
s=curl(E,X) % finding the curl of E
b=int(s,t) % integration of obtained resul of curl(E)
B=-b % Magnetic flux density
display('magnetic field intensity')
H=B/U % magnetic field intensity

output:

U =

1.2566e-06

E =

[ x^3*y^2*z, x*y^3*z^2, x^2*y*z^3]


s =

x^2*z^3 - 2*x*y^3*z
x^3*y^2 - 2*x*y*z^3
- 2*x^3*y*z + y^3*z^2


b =

t*(x^2*z^3 - 2*x*y^3*z)
t*(x^3*y^2 - 2*x*y*z^3)
t*(- 2*x^3*y*z + y^3*z^2)


B =

-t*(x^2*z^3 - 2*x*y^3*z)
-t*(x^3*y^2 - 2*x*y*z^3)
-t*(- 2*x^3*y*z + y^3*z^2)

magnetic field intensity

H =

-(4722366482869645213696*t*(x^2*z^3 - 2*x*y^3*z))/5934300740056779
-(4722366482869645213696*t*(x^3*y^2 - 2*x*y*z^3))/5934300740056779
-(4722366482869645213696*t*(- 2*x^3*y*z + y^3*z^2))/5934300740056779
