// GIVEN DATA

D = 35*10^-2;                               // Outer diameter of the conducting disk in Meter
d = 10*10^-2;                               // Inner diameter of the conducting disk in Meter
B = 1.0;                                    // Axial magnetic field in Telsa
N = 900;                                    // Rotating shaft running in RPM


// CALCULATIONS

Wr = (2*%pi*N)/60;                           // Rotational angular speed in radians/s
Er = ((D^2-d^2)*B*Wr)/8;                     // EMF induced in Volts


// DISPLAY RESULTS
