I have a question about one of the porjects on this website!

Hi, i am working on my science fair project and using one of the ideas that i found on this website. There is a piece of material that is shown in all of the pictures that is on the pages i printed out..but in the material list it is not mentioned and i think its a big part of my project. If you need to see what piece of material i am talking about. I am doing the project from this website called Recording on a Wire and the closest picture of the material that i need is figure six its the big metal thing that is in the left hand corner..you really cant miss it it the biggest thing in the picture. If you know what it is and you might know where i can find it i would really appreciate all your help and please post back as soon as possible because my science fair project is due this Friday. Thank You and I appreciate all the help that i can get.

The project is at: https://www.sciencebuddies.org/mentorin ... ?from=Home for any other experts reading this...

If this project is due on March 8, you may want to pick another project. This experiment is fairly complicated, and it will require a lot of trial and error to get it work. There are _very_ few resources on the web, which I found out when I was trying to help the last guy. This experiment is pretty cool if you have time... but if you have 1 week, it will be very frustrating and the chances are you won't get it to work in that time.

I think what you are talking about is just a clamp to hold the head in position. Everything to the left of the plate with screws (except for the one wire going to the magnet looks like positioning devices. You could probably use anything to secure the recording head in a fixed position.

hi thank you for helping me out but i just realized its due in two weeks but i still don't know what the huge metal thing is...i'm going to describe it to u to make sure that u are looking at the right thing its the picture before the section that is titled Recording and Playback and its the huge silver thing and the black thing...i have no idea what they are but it looks very big..is it something that i need to do this project? Thank you again and i will be waiting for your reply

As I said, I am pretty sure it is just a clamp to hold the magnet in place. It is behind everything else in the picture and has a rounded shape? It is a lighter silver color than everything else?

so does that mean that i don't need this part for my project? or do i need it? If so where can i bu it cause i don't understand what you are telling me it is for. Also do u know where i can buy the ferrite bead cores that i need for this project? Also is there something special that i need to make the wheel turn to record or will i just have to turn the wheels manually?

Please Help Me i need the help and i would really like it and i thank the people that have helped me so far and i hope they will keep helping me!

Let me explain how this board works. There are volunteers who check the boards- we each sign up for one day. We are all over the world- in different time zones- do not expect that you will get a fast response. Posting more and more will not get a response any faster. You should get a response within 24 hours. I happen to be working on my computer tonight, and so am responding somewhat quickly. But this isn't even my day to answer questions...

As for your questions- you need some way to hold the magnetic head. How you hold it in place is up to you. In that picture it appears that they use a large, round silve clamp to hold the magnetic head in place. You should read the instructions again carefully- this is a complicated project, and if you don't understand what I am saying and you don't understand the instructions, this is going to be very hard.

One last thing, most of us here haven't done these experiments... we can provide help based on having a scientific background, but there is no certainity that we can instruct you well enough to get the thing to work.

I don't know where you buy a ferrite bead. Several sites on the web sell them, but I really don't know if any of them are reliable.

You can either make a motor to spin the wheel or turn them yourself at a constant rate.
