Lego WhipMag Demonstration (OCPMM)
YouTube Announcement
A "WhipMag" was created for educational purpose, using nothing but Lego bricks and Lego Magnets for under $50. The configuration shown in this video was inspired by Overconfident (a.k.a. OC).

You're absolutely correct that the configuration in the video is not actually a WhipMag. I started by modeling a WhipMag, but for the purpose of the video I thought demonstrating the sticky effect was more interesting, so I reconfigured the Legos to make a device like OC's original 5-4 OCPMM.
The oscillating stator idea came from Andrea.
I should make another vid showing something that is more like the WhipMag -- a FrakenWhipMag. lol
.. Yada
The "fixed" stator magnets repel the "free" rotor magnets, causing the rotor magnets to settle down in between the stator magnets (see 00:17). It's a "magnetically sticky" area and the rotor would normally like to stay there -- even as it spins. However, the oscillating stator helps the rotor overcome the sticky area and spin more freely (with strange noises!).
Q: Will more oscillating stators help it spin longer?
A: I don't know, but it's easy to find out.
