My son and I tried this with exactly what is shown and it doesnt work Update: The wire we purchased was from an arts and crafts store, which turns out to not be real copper wire. I found a piece of electrical wire in the basement and we were able to get it to work. Check to make sure your using actual copper wire folks.
A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field. The resulting force being continuous in one direction, the homopolar motor needs no commutator but still requires slip rings.[1] The name homopolar indicates that the electrical polarity of the conductor and the magnetic field poles do not change (i.e., that it does not require commutation).

Your homopolar motor works now, that's great
Ace hardware also has "copper wire" but it is not real
@@MsBaztasticmaybe it's magnet wire and you need to burn off the insulation??

Simple Yet Astonishing 🔥🔥
Thank You Brow 🥰
how fast does the battery lose its power?
Make a dimple on the top of the battery so it stops falling off.
Okay.
Thank you.
CA glue a 1/4 in. length of plastic soda straw over the top terminal.
CA glue a 1/4 in. length piece of small diam. plastic soda straw on top positive. It will NOT fall off. I did...works great. Grandkids amazed.
Does this usage make the magnet lose polarity faster?
Im not a expert but i feel like the current from the battery would increase its magnetic flux
Don’t puncture it, but try to indent the positive side with a nail so it can be stable. I usually make an indent and a sharp, small point in the wire.
You usually make them like that? You do this often! Lol
Okay.
Thank you.
Use a dremel bit with small indentation as a running divot for it to stay in
Put the battery upside down and the coil won't fall easily.
Very cool😮
Thank you
Which materials needs?
Does it discharge the battery?
yes.
Is there a title or name for this? like the study of electricity or someting?
The homopolar motor is driven by the Lorentz force.
not working

I will try it
awesome bro
Thank You Brow 🥰

Thank You 🥰

Thank You Brow 🥰
Perpetual motion anybody?
No. The battery will lose energy.
This is a Homopolar motor
Real?
I tried this and it didn’t work! And yes I stripped the plastic off electrical copper wire to make sure it was real copper! 😭
What size wire did you use ?
This is real, I did it for my physics class in 12th grade
Copper coil?
Do not work I try it
You have a fake copper wire.
This is taught in 10th and 12th grade, it was even given as an assignment to us at the start of 12th grade.
Eso me estafo
