Imagine It - Eddy current science

A non-magnetic copper plate falling near a magnet can be slowed to a halt in just inches because of something called eddy currents.
When a magnet moves near a conductor, circulating electrical currents (eddy currents) are created in the conductor. These currents create a magnetic field that opposes the field of the original magnet.
The stronger the magnet the greater the effect. A strong magnet dropped inside a non-magnetic conducting pipe like copper or aluminum will fall very slowly.
Imagination Station, Toledo's hands-on science center, is a vital non-profit organization that is an integral part of Toledo's economic, educational and social landscape. Imagination Station provides a critical layer of science enrichment by serving as an educational partner for teachers, schools and parents. It's with a thoughtful blend of exhibits, experiences, education and excitement that Imagination Station is inspiring future generations of scientists in Northwest Ohio. With more than 250 hands-on exhibits and demonstrations, Imagination Station delivers a multi-sensory experience that's as fun as it is educational.

@ 3:30 I love how he continues playing with his stuff, when the anchor is doing his own job!!! 😂😂

[@sarthakk.c9303]

This video is awesome. I watched so many tutorials and by this video I finally understood what an eddy current is.

[@MrLonerist]

my right ear really enjoyed this

[@manojkumarsrivastava3157]

Oh I thought I have to buy a new earphone

[@huskiehuskerson5300]

What?

[@jasminepainter-durazo7384]

This was fascinating and really helpful for my physics homework, thank you!

[@vatsalmalav440]

I want to know what kind of home work was that

[@shivamanand3908]

Awesome explanation of Eddy currents. Cool!!

[@muhammadtanvir5298]

Thanks so much, nice explanation about eddy current.

[@leonardocui4969]

Finally understand eddy currents! Got 5 less fingers though but it's worth it!

[@greatking1327]

Thanks for the explanation

[@taraninaustralia4111]

Sir it is great

[@OldJoe212]

I've never seen this with flat plates, but I've seen it by dropping a magnet through a copper pipe.

[@robertpokoo-aikins6529]

beautiful

so nice of u thanks

copper is diamagnetic (ejected by a magnet), the opposite of copper is iron (ferromagnetic, sucked by a magnet) source : 'Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field.' in en.wikipedia.org/wiki/Diamagnetism

[@kiruthigakumar8557]

i thought it is moving slove due to magnetic attraction....isnt it ????

[@Tknh1]

The plate isn't magnetic. It's due to the movement of the plate through a magnet that generates eddy currents on the plate and the currents create it's own magnetic field to oppose and attract the magnets. It starts off by repelling each other then begins to attract each other once the plate is leaving the magnetic field. This is what helps slow it down so quickly.

[@unknownman8832]

It's an application of Lenz's law called eddy current that oppses the change in magnetic flux

[@renkeniko1912]

Don’t talk about it lmao imagine it, why am I dying

[@byakko-kun116]

And to say that I have to make this kind of model to represent Eddy current in my class. It seems dangerous to me 😣

The sound quality of the clip is extremely poor and as a result the conversation / comments can not be understood.

[@OldJoe212]

Trust Science.

It's not so big news when I was kid i do this
