Magnetic fields within a toroid inductor.

That's great "proof" there Dave45, a glass container filled with ice.  Is your next step going to be designing an infinitely impossible anti-gravity drive just like on the Hitchhiker's Guide to the Galaxy?

Webby1:

What if the core for a toroid was not a closed loop?  Could you then measure the current and factor in the "lossy" state of the core?

I have a testbed or 4 that are setup this way and there is a field emanating from it as well as one can be introduced as such to generate an output from the winding, so I am thinking this is not a "valid" way to test."

I am honestly not sure what the context is for your first two questions.  Can you elaborate a bit?

The A vector field can be spun........... if you know how

Hey Dave

How much power goes into your coil when you freeze the water?  Is it AC?  Have you tried it with just a magnet?

Here is another oddity found today,while looking into field strength over P/in of the rotor of the new high powered pulse motor project-the Altipulse.
Now we all know how an alternator works-right?.
Well in this video,i seem to be missing one polarity of the magnetic field???.

What a great effect you are showing here.     I wonder if a speaker magnet would do the same. If a speaker magnet did not cause the effect, then possibly a speaker magnet would work better.

What your video shows is that there is a difference  between S and N poles possibly when using a coil as compared to a magnet, or, there is an effect going on with the outer circumference of the coil and the pole fingers that is not commonly known. The speaker magnet test would be a step in the right direction. There are vids on YT that show how to take apart the armature to remove the coil to install magnets.  If there is a difference and the magnet causes the screw driver to be attracted to N and S fingers, then the coil has different attributes than a magnet of similar size and shape. I know they do, but the effect you show, Im not familiar with and it interests me.  Thanks for showing.

The reason they dont use magnets instead of coils is the regulating of the output is done by the regulator adjusting the voltage to the armature coil. Recent years there are permanent mags in alternators, as rare earths can handle some heat and the regulation is controlled at the output.
