Round Earth proof? How does this pendulum keep swinging? (youtu.be)

If I have a pendulum, it would stop swinging after like, 10 seconds

We're supposed to believe this thing swings for 24 hours a day on its own?

You've never experimented with pendulums. Why would it stop? Where is the energy going? Very little air friction, and the wire it's hanging by isn't generating much heat at the top.

Magnets in the base.

Very strange. The ones I've seen all have the magnets at the top.

How does this one work?

At the base there is a magnet that gets a current while the ball is headed for the center, this pulls the ball. Then the current is cut until the ball reaches its zenith and heads back, at which time the current is reapplied. Effectively dragging the ball toward the canter, allowing it to gain momentum while "falling" I guess you would call it.
