Rail Road Axle

%% Rail Road Axle
% Calculates the induced current in the resistor, the horizontal force, and
% the potential differnce between point a and point b

% Inputs and Variables
l = input('What is the length of the axle?\n');
v = input('What is the speed in m/s?\n');
R = input('What is the resistance?\n');
B = input('What is hte uniform magneitc field?\n');

% Outputs and Equations
E = v*l*B;
i = E/R;
Fm = v*l^2*B^2/R;
V = i*R;
fprintf('The current, horizontal force, and potential difference is :\n %e A, %e N, and %e V',i, Fm, V)
