Oops - there is a typo at 0:40 in the video. That should be 3 *cm* (centimeters) of wire, not m (meters). Sorry for any confusion!

This is the 1st ones of these tutorials that actually worked on the 1st time.

Finally i do understand how an electric motor works. It was not until a fan in a laptop broke, that i learned how a motor works, same as a engine, it needs a timing when there is 0 energy. All motors need a commutator whether its mechanical or electronic, it's the same principle like the valves of a 4 stroke engine. In this example the commutator is the moment the force of repelling makes the rotor to do half a turn, because there is an input energy higher than the needed to push the coil, it goes to the state of 0 and beyond and gravity does the rest, i wonder if you can make this with a flywheel but i assume it would be very inefficient than just using a commutator that switches the polarity of the coils. So, all motors are alternating current devices.

Thank you so much for this video and experiment cause we have a science fair in school full school and this one is the best I have ever seen

[charlie-clarkadams]

Brilliant!!! How fun. I’m going to have my students do this. They are going to love it.

[joa]

Clever way to make it with direct current, just leave insulation on! This is a great physics experiment for kids

[chadinbrackets]

any teacher watching this, please dont torture your students by building this without instructions

Reacted the project with crafting cooper wire. I utilized no paper clips only copper wire. I only sanded the ends of the piece I placed inside as suggested, worked well. I did used the a several regular magnets.

Millions of thank you by your video I can do my experiment in school thank you millions millions millions of Time 🙌✨🙃

How long does the battery operate? My child is doing a science project for school using this DIY motor to see which battery brand would last the longest. All different battery brands we used only lasted less than a minute.

[xacompany]

Simple and clever!!! Thanks for this great video!!!

[ygexrfy]

If we got rid of the battery and made a mechanism to spin the magnet wire would that be enough to have a generator?

[michelbiswas]

Cool! I got electrocuted in the process though..

[tranalley]

please show me how to fix it, I followed the instructions like your video but I used a bigger battery (maxe II) but the copper wire still can't rotate, I used a tape needle to make a pillar at the 2 poles of the battery. the battery and the magnet I use are black magnets

[jesperiso]

I wonder if the wire I used is wrong, or the magnet, does the wire need to stick to the magnet even if it is not attached to the battery? mine doesn't stick.

[playu]

If the thin copperwire breaks while building my motor, can I re-usethe copper wire together?Please sir answer my question quickly because it is my school project there

[Tocaboca-pxny]

hey so in the middle the battery is not magnetic and it doesn’t move do you have to get on that’s magnetic?? i need an answer ASAP its for my project

[theamaturepro]

Does it have to be a copper winding or could I use a copper crush washer and solder a coper rod accost it? I guess what I'm wondering is if it's the mass that matters to act as a load or if the individual wires play a part?

[aidan]

Does it really need to be coiled 10 times?

[coffin]

Help mine is not rotating ( i use safety pins, battery, thick copper wire, and small/big both magnet) what to do
