Any other electrical engineers or physicists here? BTW, Lenz's law and how the eddy currents induced in the copper piping produce a resistive effect on the magnet's magnetic field.

woooOOOOO PHYSICS!   
I just made the gif :3   
(no real physical meaning, just a fun ODE over a bunch of values)

if i remember correct they used that principle to slow down the world land speed record holder using magnetic breaks .Remember seing it on Discovery.

not an angineer and i know this, however, do you have a formula for this?

N = turns of wire(copper pipe in this case) * [Change of flux / change of time). The negative just shows how the opposing eddy currents produce an opposite flux of that of the magnet.

V=-10(7.3/10(seconds))
Delta theta= change in flux= weber (SI), right?
Delta T= change in time= seconds, hopefully?
V= volts?
-10*0.73=
-7.3 (volts? Resistance in newtons?)

Correct, also for quick theory, 1 volt = delta 1weber/second. But, that symbol was phi, not theta. But yeah, correct.

thank you very much
not sure if when i grow up i want to be an engineer or something else....

If you don't love engineering, what ever you do, don't go into it. Being an engineer is one of the worst possible jobs you can have if you don't love your work.

thank you very much sir. as i am 15(almost 16) i can barely do anything wit this, i'll make up some numbers and calculate it and you tell me if it's correct, ok?

I'm a pupil and I know this... not necessary to be an engineer

I accidentally made a heat coil once with some copper wire and a battery, if that counts.
