Triangle Loop

%% Triangle Loop
% Determines the size of the magnetic field at the center and at one of the
%    corners of the triangle

% Constants
muNaught = (4*pi)*10^-7 ;                %[T*m/A] Vacuum Permeability
arb = muNaught/(2*pi*sqrt(3));

% Inputs and Variables
a = input('What is the length of the side?\n');
I = input('What is the current of the loop\n');

% Outputs and Equations
Bcorn = arb*I/a;
Bcent = Bcorn*9*sqrt(3);
fprintf(['The magnitude at the center of the triangle and at one of the corners are:\n'...
        '%4e T and %.4e T\n'], Bcent, Bcorn)

%{
The variable 'arb' in the constants section is just a placeholder. It is
    not an actual constant. It just makes the line in the outputs and equations
    section less crowded
