This is not a homopolar motor. And a "pulsed" motor is a comutated motor if the pulse is not provided purely by electrical circuity. The whole trick to this motor is that he scraped away the thin insulation from the copper wire only on one side of the wire. That creates the commutator. For one-half of rotation, there is magnetic pull. For the other half there is no current and so relies on the rotational inertia to carry the rotor through that half of the motion. The current is never reversed; it's just turned off for half rotation. That is why people call it pulsed. But really it's just a bad commutation only mechanical switching current for half rotation. Instead of comutation switching current for one direction to the other direction, it switches current from one direction to just no current for half rotation.
Yes: it's truly commutated but the dishonest man of this channel doesn't explain how. It's simple commutation: on/off line, and not double one: with echange of electrical polarities. Not: effectively this isn't homopolar at all, there is commutation.

Hi if the number of magnet is added more what will happen to the rate of spin?
Spin will increase
So simple, good working
How long does it run for?
While not truly comutated this is pulsed and not considered homopolar.

would this work with a regular 12v DC power supply?
3v AA battery, otherwise required copper coil vending capability for 12v even magnet power.
🤔Does the wire have to be copper?
🤔🤔🤔same doubt
Yes
How long did it spin for?
when the battery power goes low then it will stop
It does not work
What size copper wire
.5 meter
How long did it spin for?
It is not homopolar motor!!! It's pulsed motor!
I do it but it not work
The secret is to erase an half part of the copper wire surface, by leaving intact the other half part.
When I tried making on something like this I got sooooooooo badly shocked/burned
If you used a AA battery, then that's a lie.

Now I am sure
What to do
This will not work
Use winding copper wire

No working
It will work, use coated copper wire.

No working.
Definitely it will work, check copper coated wire,

@@TechnologySpaceHD does it need to be copper coated? What happen if we use the uninsulated copper wire? Will it work better?
هذه الفكرة ليست جميلة ومتقنة اتمنى أن تكون اجمل منها 😢😢
