  Cosmic electrons with energies in the TeV range lose their energy rapidly
through synchrotron radiation and inverse Compton processes, resulting in a
relatively short lifetime (~ 10^5 years). They are only visible from
comparatively nearby sources (<1 kpc). Unexpected features in their spectrum at
a few hundreds GeV, as measured by several experiments (ATIC, Fermi and
H.E.S.S. among others), might be caused by local sources such as pulsars or by
dark matter annihilation/decay. In order to investigate these possibilities,
new measurements in the TeV energy region are needed. Since the completion of
the stereo system, the MAGIC Cherenkov experiment is sensitive enough to
measure the cosmic electron flux between a few hundred GeV and few TeV. The
electron signal has to be extracted from the overwhelming background of
hadronic cosmic rays estimated through Monte Carlo simulations. Here we present
the first results of the cosmic electron spectrum measured with the MAGIC
telescopes.
