绘制霍尔效应可视化图形

function hallEffectVisualization

%HalleffektVisualization 绘制霍尔效应可视化图形

%   示例: hallEffectVisualization;

% 霍尔效应的参数

I = 1; % 电流

B = 0.1; % 磁感应强度

V_H = 0.01; % 霍尔电压

e = 1.6e-19; % 电子电荷

% 生成横坐标和纵坐标的网格

x = linspace(-1, 1, 101);

y = linspace(-1, 1, 101);

[X, Y] = meshgrid(x, y);

% 计算磁场的横向和纵向分量

Bx = zeros(size(X));

By = zeros(size(Y));

for i = 1:numel(x)

    for j = 1:numel(y)

        r = sqrt(X(i,j)^2 + Y(i,j)^2);

        theta = atan2(Y(i,j), X(i,j));

        Bx(i,j) = -B * sin(theta);

        By(i,j) = B * cos(theta);

    end

end

% 计算霍尔电压的分布

V = V_H * Bx / B * e / 2 / pi / 1e-7 / I;

% 绘制图形
