In a microlensing event, at caustic crossing, flux of a spot can be magnified several times with respect of the source star. This magnification contrast provide a unique opportunity to measure the magnetic field over a source star. In this work we investigate possibility of magnetic field detection through the Zeeman effect when a source crosses a caustic line. Using Fourier analysis, one can s...
