Magnetic fields demonstration 🧲

Magnetic needles and iron filings always orient themselves towards the direction of the current dominant magnetic field. In this way, the field process of the magnetic forces becomes visible. The resulting ‘field lines’ are characteristic for certain pole constellations.

This type of tools should be available in all

I think it's also cool that you can see mechanical vibration waves propagating through the field of magnets via magnetic coupling.

Is this at a museum?? 👀👀
PS: thanks for sharing 🙏🏼🙏🏼

Great model in 2D. You can upgrade it in 3D. That would be awesome!

Better than the 40 minutes of my physics lecture 📑

Surely I've seen this demonstration at San Francisco's 'The Exploratorium' (I HIGHLY recommend visits of all ages) or 5th grade Earth science, but I'm left needing more explanation or a sort of thought bubble describing or naming 'the things/objects' in this video to truly appreciate the wonder here.
3/5 stars for effort of upload 😉

A 2D field of compass points constantly changing directions due to earth magnetic field. When a stronger magnet from a bar magnet was introduced the rate of change increases. Interesting display.

the magnet could change the polarizations of the rods therefore how they orientate, but since they arent painted to indicate polarity it doesnt appear to change anything

Meanwhile we used small particles of iron in our school days 😂

Actually great example of paleomagnetism

This is just a bunch of compsass needle type bits but even in both directions to point! Therefore there compass detects the magnetic field as usual just multiplied many times and evenly spaced out over the surface under the frames glass sheet etc!

thats the most amazing thing i have seen in my life

[adamsteller]

I wonder if you could generate any kind of electricity using the vibration of the confused toggles.

As like the bigger size magnet the small piece of magnets should also have color coting variation. Sir

In 7th line from left 3 why it's spinning all round at last...?

[Ouyemen]

What happened in the center of the toroid? Is there and infinite circle?😮😮

[verynicenickname]

why are some spinning elements stationary, while some are shaking and twitching? Yes, I understand that this is electromagnetic motion, but... why did some elements just statically change their direction, while others changed it, but at the same time they twitch...

[an_internet_user]

Stuff like this exist, while we still dissolving salt at our school...

Application: Put rod behind display, where it and its operator cannot be seen; and move it to music! The display will look like it's dancing!

This looks like the magnetic little things in big hero 6
