Magnetic fields within a toroid inductor.

[Dave45]

These pics were all taken withing a three minute window of the cell with a permanent magnet inside.

An to the next question yes I froze two magnets in repulsion, notice there are two separate fields, not a very good pic, I used tap water this is before I found bottled water worked best for clarity.

I finally got the parts in to build an adjustable test platform
I suck at electronics so it probably wont get tested as it should but I will give a go

Dave45:

Just to clarify I checked the coil for a magnetic field before I put it in water, horizontal, no magnetic field.
The coil was powered with 12v dc using an automotive bulb pulling 2 amps.

The coil had to have an observable magnetic field.  So there is something wrong there.  Perhaps you could post a pic of the coil so we could try to understand why you did not observe a magnetic field.

Hey MileHigh
The coil was wound and connected specifically so it would not have a magnetic field, so as to cancel its own field.
Rather than try to explain I will draw it out later this evening, Im busy at the moment, honey do this honey do that, no rest for the weary.
