Write your drawframe function below
function drawframe(frameNumber)
% Parameters
numPoles = 4; % Number of magnetic poles
rotorRadius = 1; % Radius of the rotor
coilLength = 0.5; % Length of the coil representation
% Create figure
figure;
hold on;
axis equal;
axis([-1.5 1.5 -1.5 1.5]);

% Draw the stator poles
theta_poles = linspace(0, 2*pi, numPoles+1); % Angles for poles
for i = 1:numPoles
% Calculate position for the poles
x_pole = 1.2 * cos(theta_poles(i));
y_pole = 1.2 * sin(theta_poles(i));
% Alternate North and South poles
if mod(i, 2) == 1

else
text(x_pole, y_pole, 'S', 'FontSize', 14, 'FontWeight', 'bold', 'HorizontalAlignment', 'center');

% Draw the rotor
theta_rotor = deg2rad(frameNumber * 10); % Rotate rotor by frameNumber*10 degrees

% Draw coil arms of the rotor
