| Sumario: | We present an experiment conductive to an understanding of both Faraday’s
law and the properties of the superconducting state. It consists of an analysis of
the motion of a superconducting loop moving under the influence of gravity in
an inhomogeneous horizontal magnetic field. Gravity, conservation of
magnetic flux, and friction combine to give damped harmonic oscillations. The
measured frequency of oscillation and the damping constant as a function of
the magnetic field strength (the only free parameter) are in good agreement
with the theoretical model. |
