We present the first demonstration of a three grating Talbot-Lau interferometer for electrons. As a proof of principle, the interferometer is used to measure magnetic fields. The device is similar to the classical Moire deflectometer. The possibility to extend this work to build a scaled-up charged particle deflectometer or interferometer for sensitive magnetic field sensing is indicated.
