  1. Hey thanks for showing me how to make this! One question: I can only find 1.5 V 40 mA mini bulbs at Radio Shack, I've called around but all the stores near me are sold out of 25 mA. I saw on your website you use a 40 mA also, should this work?

  2. What grade would this project be recommended for? I'm in the 8th grade, would this be suitable? i find it very interesting. Please answer asap as i will need to prepare a report very soon. Thanks! 🙂

  3. I'm having a lot of trouble finding the 1.5 volt lightbulb… Do you know any CANADIAN sites I can order from? Other stores are charging 30- 50$ for shipping!

  4. Hello I am working on this for a science fair and can not get the bulb to light. I have the same radio shack bulb. I don't think i have the wires correctly placed. Does it matter which wire goes on the long leg of the bulb? I have the last wire (meaning not the one i taped to the box) on it.

  5. i have a physics project to build an alternator like yours, but the twist is i need to generate a minimum of 25V what do you suggest i do?

  6. where exactly did you tuck the first end of the wire?

    is that the other pole you attached to the light? i didn't notice where you had it

  7. Hi, Thank you for showing us how to do this. Since you posted this video Radio Shack went out of business. Do you have recommendations as to where else i can purchase these items? Specifically the light bulb. I'm having a hard time finding the correct one.

    Bhai log isse dekhna mat bhoolna or ho sake to comment and subscribe bhi kar lena 🙏🙏 apna blog ha

  9. @wbeaty can i do this experiment with a larger cicumference copper wire instaed of a thin copper wire …..????

  10. I'm having a miserable time finding magnet wire. (locally) Is beading wire the same thing? Or is that something different?

  11. Fake video .It did not worked ..I tried this..
    Is any one who successfully made it..??( Sure not anyone )
    And it is not for any school or college project.Your teacher will throw it away…

  12. This is single phase, i know. But, what if I wanna Bust-A-F*** some LEDs, can this be easily converted to 3 phase generator?

  13. Would the magnetic feild reach the the outer wire loops if i used #35 wire and did 3000 loops with rare earth magnets?

  14. I followed the instructions on your website with slight changes (i added about 4 times more wire) and the 3v bulb i powered kept flickering on and off is there any way i can make it stay on?

  15. On the website you gave instructions to make a more powerful generator, and i would like to know if it is necessary to use smaller wire and why.

    Thanks

    Ps. Would it get 120 volts?

  16. You can find something like this on the Avasva page. Full step-by-step instructions right on your desk.

  17. Today My son and I made this generator. So simple! It's working! I love science! thank you

  18. 6:53 My class is laughing there heads off at this part. In fact, my class laughed at every part, they should act like a middle schooler. (the thing is that my whole class is a middle schooler.)

  19. 4:09 I need this for my model in science class and I couldn't see this part like, did you wrap it around the magnet? Did the wire come out of the other side? I'm confused..

  20. does a stronger magnet provide more power or is it all in the amount of turns or thickness of wire?

  21. First of all, let me tell you what material I have used.

    Cardboard – size as mentioned in the instructions

    nail – more than 8 cm long

    copper wire – 120m length – https://www.jaycar.com.au/0-315mm-enamel-copper-wire-spool/p/WW4013 (picture attached for ready reference)

    magnets – 4 bars – https://www.teachersource.com/product/ceramic-magnets/magnetism-magnets

    My queries where I need help from you:

    1. Kindly confirm if the material that we are using are the correct ones. We can not buy anything from Radio shack as advised in the video because they do not deliver in Australia.

    2. In the video, the guy mentions to use some kind of spacer between the magnets. What that spacer is and how to use it.

    3. Instead of cardboard, can we use plastic or acrylic sheet, like it is shown in the starting of the video?

    We are really relying on this video to make the simple generator and win a prize in the school science competition.

    Your help in this regard is much needed and highly appreciated.
