I did focused on angular oscillation paterns of floating magnets in my
experiments. I observed wide range of epitrochoidal angular oscillations as a
result of forces between the spining base magnet and the spinning floating
magnet. I only observed two cases where oscillations have hypotrochoidal
pattern. From web search such oscillations did not phenomenically reported in
general except path of particles in traps, I found. Most of recent videos I
uploaded to YouTube scoped on these oscilations where floating magnet spin is
locked to base magnet spin.
