Steel Beam Dropped

%% Steel Beam Dropped
% Determines the induced EMF in a dropped beam before it hits earth's
%   surface

% Constants
g = 9.81;                   % [m/s] Acceleration due to gravity on Earth

% Inputs and Variables
l = input('What is the length of the beam?\n');
h = input('What is the height at which the beam is dropped?\n');
Emag = input('What is horizontal component of the magnetic field?\n');

% Outputs  Equations
v = sqrt(2*g*h);
E = v*l*Emag;

%{
Under the assumption that the beam's long dimension remains in a
horizontal field, oriented perpendicularly to the horizontal component of
the Earth's magnetic field
