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
