i stuck the magnets closer to armature with hot glue and when i gave it a big enough force it actually spun for around 15 secs! I'm going to align the paperclips at 180 degrees as suggested, determine the polarity and hope that it continues to work otherwise i'll buy some more magnets to stack...

there is a small force! when i give it a jump start, the commutator rotates a bit on its own but it won't continue. i'd upload a video but it won't let me

the magnets are definitely attracted to each other - i tried determining the exact polarity using the phone compass but it didn't work (kept pointing to west) and i don't have a physical compass so i think ill borrow a magnet from school tomorrow and test it out. i did also reduce the gap but...

okay so i shortened my dowel and armature to reduce the mass, and used a thinner coil (0.4mm) for the turns (80), i also took your suggestion to use the pin bearings but the motor still isn't working. i'd appreciate any more suggestions you have. here's an updated pic:

ahh this is very helpful thank you soo muchh - i'll try it out and hopefully it'll work

this is the video i followed

oh i hadn't even thought about an iron armature - do u have any ideas how i would make/buy one?

the youtube video i was following said to sand off the enamel so i did lmao - i'll post the disassembled pictures in a few hours when i get home

i wound them around a wooden armature - i will clarify the magents and assess what you've suggested, thanks!

yeah there is 0 force, i even tried giving it a kickstart to get it moving but it doesn't seem to work. I'm not sure what you mean by single coil but i have arranged the magnets as you've suggested.

hi everyone, i need to build a dc motor for my school project. I have used copper wire for the turns (60 turns), wood to build the structure of the armature and commutator. i have used neodymium magnets as my permanent magnets and paper clips as the brushes. I tried using a 9v battery with a...
