10. Magnetic Gears (IYPT 2024)

Where did you buy that? We need to do the experiment and we hope the gears are the same

Is the video sped up? And can you tell which magnets are facing north and which south

Bro what size of magnets do you use pls reply me i really need to do this test

Does it have to be a flat magnet

I have trouble designing this experiment, how can I change the parameters and analyze the data?

Can you tell me the size of magnets & diameter of fidget spinner?

It also seems like the fidget spinner is made of metal. Wouldnt that affect the observation due to interaction with magnets?
