      abstract     = {Free electrons with a helical phase front, referred to as
                      “twisted” electrons, possess an orbital angular momentum
                      (OAM) and, hence, a quantized magnetic dipole moment along
                      their propagation direction. This intrinsic magnetic moment
                      can be used to probe material properties. Twisted electrons
                      thus have numerous potential applications in materials
                      science. Measuring this quantity often relies on a series of
                      projective measurements that subsequently change the OAM
                      carried by the electrons. In this Letter, we propose a
                      nondestructive way of measuring an electron beam’s OAM
                      through the interaction of this associated magnetic dipole
                      with a conductive loop. Such an interaction results in the
                      generation of induced currents within the loop, which are
                      found to be directly proportional to the electron’s OAM
                      value. Moreover, the electron experiences no OAM variations
                      and only minimal energy losses upon the measurement, and,
                      hence, the nondestructive nature of the proposed technique.},
