Windowed FFT magnitude / leakage effect

Hello,
i am doing an windowed fft to get the magnitude by a frequency.
But the result of the magnitude is not the magnitude of the sampled summation of sinusfunction, which i defined.
This effect is the leakage effect and i heard about a correction factor to get the right magnitude from the windowed fft.
Thank you for help!

Hi,
You may calculate & apply Amplitude correction factor to compensate the leakage effect. Here is an example
N= 100;
w = hann(N);
% correction factor
Cf=length(w)/sum(w);
