We discuss the feasibility of detecting magnetic transitions with electron vortex probes, suggested by selection rules for the magnetic quantum number. We theoretically and experimentally investigate the dichroic signal strength in an electron energy loss spectrometry experiment. It is shown that under realistic conditions the dichroic signal is undetectable for nanoparticles larger than ~1 nm.
