Eddy Current Tubes

Eddy Current Tubes -- Drop the Magnets down the tube. An eddy current is set up in a conductor in response to a changing magnetic field. Lenz's law predicts that the current moves in such a way as to create a magnetic field opposing the change; to do this in a conductor, electrons swirl in a plane perpendicular to the changing magnetic field.

Because the magnetic fields of the eddy currents oppose the magnetic field of the falling magnet; there is attraction between the two fields. Energy is converted into heat. This principle is used in damping the oscillation of the lever arm of mechanical balances.

That's oddly relaxing to watch.

Lenz's Law in action! Interesting!

That was really cool to watch. I'm currently learning about Lenz's law in my college electronics class.

O MY GOD.........EDDY CURRENTS!!!!!

I just answered it perfectly through reasoning in one of the questions from Griffith. But now that I see it, wow! It's so pronounced...I just didn't know..never tried, even at lab. Great effect of eddy's current :)

Which way should be the magnet magnetized? And how to calculate opposite force by eddy currents? Thank you

[Oshyrath]

The explanation of how it works... The science behind it... According to Newton's... Shit, this thing is magic.

[MortimerKahn]

Fucking magnets! How do they work?

Oh My God... What is THIS?? I can stand talking dogs, flying fishes and invisible dragons, but THIS?!? The world's end is near.
