A magnetoelectric composite transformer is proposed. The voltage step-up ratio can be adjusted by an applied magnetic field based on the direct and converse magnetoelectric effects. The nonlinear relationship between the voltage step-up ratio and magnetic field is caused by the nonlinear relationship of the magnetoelectric effect in magnetic field.
The NUADU (NeUtral Atom Detector Unit) instrument aboard TC-2 recorded 4л solid angle images of charged particles (E >180 keV) spiraling around the magnetic field lines in the near-Earth plasma sheet (at ∼ −7 RE, equatorial dawn-to-night side) during a geomagnetic storm (Dst =−219 nT) on August 24, 2005. Energetic ion beam events characterized by symmetrical, ring-like, solid angle distributions...
