Oct 20, 2008 - I'm afraid that's a consequence of short attention spans. I'd suggest hitting pause when need be, and be sure to watch the previous videos mentioned in the title screen. They help lay the foundation you need to understand what's going on without seeing every little detail. Also, there's a link to the transcript in the video's description.

Oct 21, 2008 - I dont think "short attention spans" have anything to do with not being able to catch details in something put in fast forward. I'm afraid that assumption is a consequence of arrogance. Also, it's hard to hear all of your words with your background music. That goes for the few videos of yours I've watched.

dcolarusso Says:

Oct 21, 2008 - To clarify, I developed the video with short attention spans in mind. My goal was to spark viewer interest, hence the fast-pace and background music. I did not want it to be a dry step-by-step video. I am sorry if you expected something else. Again, if you have difficulty hearing the words. I have provided a transcript in the description. I also assumed that given the format, hitting pause and watching for a second time were options. Watched the previous videos in the series is also helpful.

Oct 30, 2008 - where can i buy the welctricity , andy2xx, and what is it !.LOL>

Kiusro Says:

Oct 30, 2008 - I think that this is the simplest way for anyone to understand the movement of an elecrtric motor, very good ideea, keep it up ;)

Nov 1, 2008 - what kind of wire was that????

TeteProductions Says:

Nov 1, 2008 - What if the wire was magnetic couldn't that create perpetual motion?

elmeister4evayoknow Says:

Nov 4, 2008 - hey, what kind of magnets are these? ferrite ones, ceramic ones, neodymium ones?

mileyhatersrwelcome Says:

Nov 6, 2008 - that thing is soooo awesome and its so simple

Nov 7, 2008 - Nice setup, by the way can you tell me what song is used for this video? I really like the background music especially with it's "jazz" feel in it..thx

Nov 8, 2008 - The song is "Time to Funk" from Trafic de Blues, as mentioned in the credits and you can find them over at Jamendo.

Nov 11, 2008 - perpetual motion is physically impossible.

Nov 12, 2008 - wut did u strip. the two ends ???? i need help this is my science project :((

diabolomanpaino Says:

Nov 13, 2008 - could u do it wid a battery

eyeieuan Says:

Nov 14, 2008 - you sound like dave off dude wheres my mount

muzike02 Says:

Nov 17, 2008 - in this video you can see the application of electromagnets and electromagnetic induction in electromagnet if there is an iron surrounded by a coil that has a current flowing in it causes the iron to become a magnet and while in electromagnetic induction the change in the magnetic field induce electricity. so more loops of coil more electricity and magnetic field so the coil moves faster

Nov 19, 2008 - U DIDNT EVEN SHOW US HOW TO MAKE IT

dax000ah Says:

Nov 22, 2008 - I made one in about 10 minutes but it took a lot of tweaking to get the right balance and distance of the loop from the magnet. It works though.
