Query: Reexamination of Barnett's Experiment Based on the Modified Lorentz
  Force Law   Barnett's experiment demonstrates that the induction on a stationary
cylindrical capacitor in the presence of a rotating magnet or solenoid is zero.
In this investigation, based on the modified Lorentz force law, which complies
with Galilean transformations and depends on relative velocities, the induction
on the capacitor is reexamined. When the rotating solenoid is long and the
capacitor is placed inside the solenoid, it is seen that the induction actually
vanishes as observed in Barnett's experiment. However, when the capacitor is
placed outside the solenoid or when the solenoid is short, it is shown that the
induction can departure from zero. This prediction provides a means to test the
validity of the modified Lorentz force law.
