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).

  • JavaLessons,

    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

  • JavaLesson,

    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.

    ..Yada

  • Aha, I see, but that's not Whipmag, actually.

  • Why the fixed stators ?
