Am I getting this right?

that blue shit in the middle is a conductor and the green surrounding lines is the primary magnetic field

the yellow line circulating the magnet is the eddy current

and then the yellow rings on the side is the secondary magnetic field, opposing the primary magnetic field

@rocknrollkunt The green lines are the magnetic field lines, the blue area is the area bounded by the red conducting wire loop. Lenz's Law is stated in terms of changing magnetic flux, which is how much magnetic field (green) goes through the area (blue).

When that flux (blue graph) changes with time, it drives a current with an EMF (yellow graph) which drives a current in the loop (yellow loop). The yellow loop induces a secondary magnetic field (yellowish green lines)

Also, what software did you use to make this?

[mrg3]

@RylyC I use POVRay to create the frames of the animation, and virtualdub to sew them up into an avi file (with compression)

its crap. when you drop a megnet trough a copper pipe the magnet try to align a mangetic field with it in the copper but since the change in electric resistance reuslt in the creation of electron source dipole it can then produce another change in electric resistance that induces a magnetic source dipole in opposite direction of the magnetic field that induced it. its the electric source dipole that induce lenz law magnetic repulsion between the magnet and the copper pipe i think.

@coldarc This animation is ONLY on the induced current, it doesn't try to show the interaction between the induced current (and resulting dipole) and the field which crated it. I don't know what you are trying to say about "change in electric resistance".

cant understand ...god i hate my teacher worst in the univers

[Ortmoon]

Wow, I can't even understand this.. ARGH !!

didn get any of the shit

hey do you thick that aposing magnetic field is antigravity like using aluminum and a 240 tune coil by tunning it to the right frequency it will lighten in weight this is said by senior boyd bushman he worked for lockheed martin its on youtube just type boyd bushman

@rocknrollkunt the green lines (or blue) are magnetic flux/field, the yellow circles are the magnetic field that is induced by the current.

As the magnetic flux changes (the magnetic field lines number moving from low to high) , the ring (or conductor) would be induced with current, and hence produce a magnetic field (yellow lines)

and no, the brown ring is the conductor. the blue part is to just illustrate how much flux lines are passing through the ring, inducing current in the ring.

[rocknrollkunt]

@rocknrollkunt circulating the conductor i mean

This animation is great. Thank you!

@coldarc to sum up just read his last two words

[kelvinlo125]

it's really complicated
