Working Attraction Magnet Motor on Youtube!?

Hi Sean,
I guess with these small diameter magnets your screw head just sticks too much..
You probably need to grind them off or use bigger diameter magnets, so the flux
will reach out also to the end of the screw and also attract this.

Can you post a video and show exactly where it still sticks ?

Hi Sean,
well quickly done.
Maybe your magnets are a little too small.

I think it really depends also on the exact sizes
you use.
Good luck.

Hi Hart

Looking at the original video again, I would say he is using close to 5mm rod magnets.

If I bring the arm within say 5mm of the screws and spin the Rotor by hand, I can certainly feel the vibration and interaction from the magnets acting on the screws. Also they ripped a couple of screws off that had to be re-fitted LOL

I tried some 10mm rods but way too strong and also some 6mm cube magnets, but trying to keep it a little bit close to the original LOL

Would love some feedback by the original artist, so lets hope he pops back in.

Cheers

Sean.

Sorry, I wasn't clear. I was commenting on @xpenzif's video.

Ah sorry mate, confusion again LOL

Cheers

Let me do a quick shoot

Hi Sean,
I had another closer look in fullscreen modeof the original
video of user xpenzif
and I can see now, that the screws are really all very well
grinded off and that there sticks no "hill" out at the head,
so this makes a huge difference to your unit, as
the distance from the magnet to the screws does not
change much in xpenzif?s video, but just the thickness
of his iron mass of the screw.

In your replication, as there is the "hill" of the screw hat
you have much bigger attraction forces to overcome
due to the nearer distance which goes into a square factor !
in the attraction formulars
and thus it is far more sticky.

I hope you still can change your screws by grinding off the heads
enough.
Just as another user said, screw a few of them into wood and use
a grinding tool to braze  the head "hill" off at one side or (both sides ?)


Good luck !

Regards, Stefan.
