i want to say thanks to everyone for hellpin me out sooo much
the science fair is this tuesday and i think i have a good chance of doing well i have been workin on it nonstop and its payin off
THANK YOU

and especially i want to say thanks to clif_j for...
please excuse me if this is a domb Q but wht were the mmmmmmm pppppppp mmmmmmmmm aaaaaaaaaa gggggggggg eeeeeeeeee nnnnnnnnnn rrrrrrrr sssssssss and tttttttttt sopposed to be??
and is the string and pully hooked up to the top magnet or some pieces of paper? (i don't understand the diagram)
my magnets are weird
they will repell but if u twist it the will attract
its like noth and south are an the same side and the whole magnet is split in quarters! it has 2 south poles and 2 north poles

actually i tryed that already i don't know why it didnt work but it didnt
i am in a jam now
i need help almost all the projects you guys have said eather iv tried or the just bore me i like the inductrack idea but i need to know how to make it bounce back and forth
and i don't need...
i really didnt have any other ideas so...
i was thinkin that to get it goin i could just start it goin that fast manualy and then make it bounce back and forth until is slows down. that way i don't have to worry about the linear motor and propultion and that stuff.
would that work??
and i...
im goin up against magnetic generators ,huver crafts , ex. (and then there is the classic volcano)
now cliff were u saying that it is possible or that i probably won't pull it off?? and if you are saying that i CAN do it than i have a couple Q.
1. so are you saying that i can just put...
i know u all want me to give up on this one and move to another one but i will need to do this project in order to beat out the other kids in my class (they have good projects)
i am useing the polls but its not working...
to make the hallbock array do i need to buy a bunch of square mabnets and put them in the order shown on the diagram?? how do i make the hallbock array
and could i use circular magnets to acheave it or do i need square or rectangle ones ??
nnnnnooooooo that's no what i meen its not a flat base. its a biger piece of pipe that fits AROUND the track ot on top of it (that way it will have stabillity) it looks like this

what would hapen if i wraped the whole thing in small wire and use permanant magnets on the train
then i used a toggle switch and a dimmer switch
will the train move with current against the current or will it just sit there??
...then will the train slow down if i "dim" the current going...
i already tryed to use perminent magnets :frown:
i looked up linear moter online and i got nothin but deffinitions of what it is nothing aboult how to make one
does anyone have a plan on how to make one?
what should i do to the trak if i can't just wrap wire around it ??
all the...
