The power output of the acrylic and Teflon devices with rail were
similar at 410 W and 392 W, respectively, when vertical. They
have similar power output because the estimated damping force on
these devices is similar at 0.001 and 0.0008 N, respectively. Additionally,
the displacement of the levitating magnet is limited by the
box height, and therefore the power output is limited. The results
show that the acrylic device has slightly higher power output, but their powers are close enough that the difference can be attributed
to fabrication and measurement tolerance. As seen in Table 2, the
difference in power becomes more pronounced at 0.075 g, with 304
and 326 W, for acrylic and Teflon with the rail, respectively. As
the acceleration decreases the damping has more of an effect on
the acrylic device.
