What Happens When Neodymium Magnets Reach terminal Velocity?

Here are some words from the home experimenter on the challenges and successes he encountered:

So i was not sure what exactly is going on here from a force stand point so i asked someone smarter this is what he told me…
“This is a classic angular rotation/centrifugal force (or is it centripetal?) Problem. As the angular speed increases, the force required to keep it together increases (obviously). The fun comes in the hexagonal structure of the overall mass and the “subcells” ill call them. The radial force is transferred through the lattice using these angular “bonds”
“The fun part is determining if it flies apart at the edge, or further in because the inner bonds have to resist the outward acceleration of all subcells further out. I bet the first delamination occurs at the point where the air contacts the mass. That exact point has to deal with the force of the air and the magnets. “

We hope you like the video and don’t try this without the supervision of a professional!

    U know what i love science! And i love the science u guys post. But i cant handle all the spam and advertisement u allow on ur page. Im sorry ima have to unfollow.

    Terminal velocity is the maximum speed something can reach while falling through the atmosphere against the force of air resistance. This is just a ball of magnets spinning……

    Not really sure why thats hard to believe. Theyre not welded together. Of course when you spin it fast theyrr gonna fly apart when the centrifugal force is greater then the megnetic force. Basic physics

    Is there some other meaning for “terminal velocity” that I somehow missed? This has nothing to do with terminal velocity. LOL.

    I love when pages post bullshit to try and suck people in to their ads.. Don’t even have to click it.. all ready know exactly what happens.. one force overcomes another.. magnets probably shoot out in all directions.. anticlimactic ending.

    Cyberlink Powere Director sucks. They do not supoort the software once you purchase it. I had a registered copy and they could not find my information.

    with a bit of sensor work we’d know how fast. with a second air gun we’d eliminate the inaccuracy due to the wobble. With some actual numbers we’d have science. until documentation and experimentation its not science and its just goofin off.
