Flexible Wire Loop

%% Flexible Wire Loop
% Determines the magnitude of the average induced electromotive force
%    during the stretching process

% Inputs and Variables
r = input('What is the radius of the loop?\n');
B = input('What is the magnetic field ?\n');
t = input('Time it takes to stretch the loop\n');

% Outputs and Equations
E = B*pi*r^2/t;
fprintf('The average EMF is %.4V', E)
