The Mystery of Magnet Rotations: An Unanswered Question

[Hir]

This happened a long time ago, and I haven't found the answer. I posted a post on the Internet, and no one gave an explanation, so I really hope to find the answer.
A magnet, no matter which pole is facing up, will rotate counterclockwise, as shown in the figure below.

The magnet will not spin after it is demagnetized.
With iron of any shape it will not spin.

Too much detail xD

You have to give more details so that anybody who read this can reproduce it.

By your description, you have proven that magnetism has nothing to do with the rotation. So we're left with "sometimes it rotates and sometimes it doesn't."

The magnet never rotates after demagnetization, and neither does the same shape iron, so if you can, experiment yourself.

 

[malawi_glenn]

so if you can, experiment yourself.

What is the point of all your threads on magnetism lately?
This "experiment" is not very well explained. After all, you could have had the string twined from the start and get the same effect.

I am very angry.

Here there are only experimental results, no videos of fooling people. If you don't believe it, you can do your own experiments, and the cost is extremely low.

demagnetization

You keep using that word. I don't think it means what you think it means.

If it spins clockwise north end up and clockwise south end up, what will happen if I have two magnets magnetized in opposite directions? Clockwise, right? Ten magnets? A thousand? A million?

"Unmagnetized" iron has many tiny domains, some with north in one direction and some with north in the opposite direction. So it should also spin clockwise. But you say it doesn't. By your own words, you have proven magnetism has nothing to do with what you claim to see.

You can be angry all you want. But not at us - your own observation contradicts your explanation. That's science.

Why metals without magnetism never rotate, it doesn't matter if you think this phenomenon is not worth discussing.

no videos of fooling people.

Then at the very least make videos with a much wider field of view, ideally with multiple cameras.

If you don't believe it, you can do your own experiments, and the cost is extremely low.

You think we have never played with magnets? You seem to be the only one observing this phenomenon. It is up to you to prove that there is no trickery involved.

 

[malawi_glenn]

I am very angry.

I do not care about your feelings.

you can do your own experiments

You have not provided enough information for anybody to reproduce your findings. I do not even know how to place my magnet, I do not even know if you have a magnet, I do not even know what string you use, and so on. This is a science forum, you need communicate scientifically i.e. using the scientific method.

This thread explains it all I think https://www.physicsforums.com/threads/an-oriental-with-low-education-background.1051208/

Try using a non-twisted string. Dental floss would work well. If your magnet still spins let us know at this forum. Don't be angry.

I don't think the world should be like this. I have clearly informed the result, but no one believes it. Therefore, no matter how good the video is, it is futile, because most people only believe in authority.

I have noticed this phenomenon for at least ten years. If you think it is a problem with the rope, you should use it to hang other things, and I have tried it.

 

[hutchphd]

My magnets do not spin.

My magnets do not spin.

The torque is very small, and the center of gravity must be found. The thread used in the video is used to make clothes. If you have any questions, please take a picture or video.

 

[malawi_glenn]

The thread used in the video is used to make clothes.

Those threads are twinned. Try a thin copper thread like 0,1 mm

Therefore, no matter how good the video is, it is futile, because most people only believe in authority.

We in here believe in the scientific method.

Yes, it does explain a lot about the OP's motivations:

In the future, I plan to discuss "perpetual motion machines" in the forum. My goal is to change the world and I strive for truth; please don't stop me before there is no evidence that there is a problem with my design！

Since the video is clearly a fake, this thread will remain closed.
