A thick-walled sphere rotating in a uniform magnetic field: The next step to de-spin a space object
作者：Mark A. Nurge , Robert C. Youngquist
来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.596-610AAPT
摘要：Modeling the interaction between a moving conductor and a static magnetic field is critical to understanding the operation of induction motors, eddy current braking, and the dynamics of satellites moving through Earth's magnetic field. Here, we develop the case of a thick-walled ...

    Zeeman effect experiment with high-resolution spectroscopy for advanced physics laboratory
    作者：Andrew S. Taylor , Alexander R. Hyde , Oleg V. Batishchev
    来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.565-574AAPT
    摘要：An experiment studying the physics underlying the Zeeman effect and the Paschen-Back effect is developed for an advanced physics laboratory. We have improved upon the standard Zeeman effect experiment by eliminating the Fabry-Perot etalon, so that virtually any emission line...

      Determining the muon mass using a scintillator-based detector
      作者：Neal Woo , John Essick
      来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.611-618AAPT
      摘要：A scintillator-based detection system, of the type employed in the popular muon-lifetime instructional lab experiment, is used to measure the muon mass. The photomultiplier pulse pairs produced by the decay of cosmic ray muons into product electrons and positrons within the ...

            Artificial circumzenithal and circumhorizontal arcs
            作者：Markus Selmke , Sarah Selmke
            来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.575-581AAPT
            摘要：A glass of water, with white light incident upon it, is typically used to demonstrate a rainbow. On a closer look, this system turns out to be a rather close analogy of a different kind of atmospheric optics phenomenon altogether: circumzenithal and the circumhorizontal halos. Th...

              Transient heat conduction in a heat fin
              作者：Jed Brody , Max Brown
              来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.582-586AAPT
              摘要：We immerse the bottom of a rod in ice water and record the time-dependent temperatures at positions along the length of the rod. Though the experiment is simple, a surprisingly difficult problem in heat conduction must be solved to obtain a theoretical fit to the measured data. T...

                Concepts first: A course with improved educational outcomes and parity for underrepresented minority groups
                作者：D. J. Webb
                来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.628-632AAPT
                摘要：Two active learning physics courses were taught and compared. The “concepts first” course was organized to teach only concepts in the first part of the class, the ultimate goal being to increase students' problem-solving abilities much later in the class. The other course wa...

                  Dust ball physics and the Schwarzschild metric
                  作者：Klaus Kassner
                  来源：[J].American Journal of Physics(IF 0.782), 2017, Vol.85 (8), pp.619-627AAPT
                  摘要：A physics-first derivation of the Schwarzschild metric is given. Gravitation is described in terms of the effects of tidal forces (or of spacetime curvature) on the volume of a small ball of test particles (a dust ball), freely falling after all particles were at rest with respec...
