// 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
