Unusual magnetic phenomena observations are found in this SinkScience #7 video.

First, we see a rotating and revolving ball magnet in a pyrex bowl. The revolving was expected; the rotating was not. Is this the same phenomenon as the Earth rotating around it's axis as it revolves around the Sun?

Secondly, we see a ball magnet inscribe cloverleaf patterns in a pyrex bowl at lower rpms, in circles and ellipses as the speed is increased.

Third, and most important, is the ball magnet suddenly reverses direction at high speed, and revolves faster and smoother AGAINST the prevailing magnetic field than it did with it. Surprisingly strange behaviour!
Eddy currents? Magnetic lag? Weird alien technology?

Explanations are welcome!

YouTube user AdminOnDuty has suggested in the comments that the magnetic ball is influenced by the catenoid space of the magnetic field of the magnets of the turbine, and something called the event horizon.
Here is a link to a diagram of the catenoid magnetic lines of force:
