Magnetic propulsion Magnets using earths magnetic field

Two 20mm x 50mm x 10mm C5 ceranic magnets suspended on 2600mm cotton thread any length of thread will work.Experiment to show that the magnets will only rotate for a length of time anticlockwise until the thread is tensioned and then slow and stop.
Used thread for least resistance and maximum spin.It has been proposed that this effect is only inertia but you cannot mach the clockwise spin with the anti clockwise they are not the same and you have to manualy sin clockwise and it does not speed up.This can be replicated probably anyhere, what useful purpose this has I have no idea just an interesting phenomenon. There is the only the tension of suspension medium that stops the rotation I have done this many times, spin times according to different lenths.Any magnet should do just position south face to north at an angle and let go. Video doesn't give the best effect of the spinning try it youself.

Virilianninja, Thanks for comment if you havn't already take a look at the Orion Project.org. As for me I'm working on my bedini window motor generator combo to grid tie it and reduce my electric bills. There's not a useful 0 point energy machine in the public domain yet for whatever reason plenty of conspiriacy theories though.

realjoefriday fair comment thye reason why compasses don't spin is mass and friction also they float in an oil bath.The cotton sewing thread is twisted in its manufacture but it has no torque to turn anything .All it offers is little initial resistanc at beginning to turning motion until wound up by the magnet ,the time taken to do this depends on the mass of the magnet and inertia created by the accelerating spin and is eventually stopped.

Jdsteen96002 good to hear you gave it a try, the larger the magnet and longer the thread the longer it will spin for. I tried for the same effect by fixing a needle to the base of a magnet and the point bearing on glass but weight and friction stops it from continually turning.If anyone could over come that we would have perpetual motion!

Thanks for comment yes I have reversed the thread and same result. I have suspended a 10oz 75mm dia x 20mm ring magnet out of a loadspeaker and that spins very fast.I have fixed a 12" hacksaw blade to the magnet in the video and counted the speed increasing from 0 to 52 revs a min at 3 mins then decreasing 2 revs per min after that.Again effect only works anticlockwise.If you have a magnet give it a try.

You're mistaking the cause for the effect. It's your thread that's unwinding or relaxing that's causing the spinning. The thread gives only a tiny amount of torque, which is why the magnet can *stop* the torque from the thread.  When you give it the initial "nudge", you overcome the original stopping force, but the only energy you're showing here is the original twist in the thread. If this demonstration were correct, then no compass on earth would ever stop spinning after getting started.

do same thing, back off, and show full view off both

Very interesting. You get a lot of unscientific criticism. I agree with others who say "silence the debunkers" by zooming out or filming in a space large enough to frame all magnets and the full suspension system. You haven't proven that no one is manipulating from out of frame yet. God bless!

@tinablvns Yes!

@aneuryism Very rare to see anyone (including myself) step up and replicate an experiment on social media. Thank you. Did you record it?

[TheAdmiston]

heY!! It's all because of twisting the thread !

[aneuryism]

I repeated this experiment at home. The result was the same. However, I also suspending a non-magnetic weight from the string instead of a magnet. The same thing happened. The sewing thread is twisted in it's relaxed state. When a weight is suspended upon it, a tension is created in the string. As the string releases the tension & extends slightly-potential energy is converted to rotational energy. The direction of rotation is dictated by the direction of the string's twist. No Magic.
