Magnetic fluid and machineable ceramics

[Opcom]

Maybe it's been seen before but anyway..

MACOR - from Corning. MACOR could be an answer to broken or custom insulator needs.

I was looking for magnetic fluid which led me to Magnaview.

I want to look at the magnetic field between two pole pieces.

There isn't much there about how to use it so I searched through a bunch of stuff. Some of it was pretty weird. In finding our more, I happened upon MACOR.

So in addition to the Magnaview magnetic fluid, here are some good links to the MACOR machinable ceramic.

(here are the weird things. weird science basement tinkering videos, It's not clear what they are doing. may be disregarded, might be entertaining:)

you won't be able to look at the magnetic field with the ferromagnetic liquid you linked to. Its presence in the field alters the field lines (it distorts the field between the poles). Maybe iron fillings sandwiched between two glass plates (with a wood frame and a wood handle so you can move it around) will be a better indicator of the actual field.

I'm glad you told me that and saved me some money!. I want to see how uniform the field is between the poles of an old klystron magnet and a WWII magnetron magnet.
Thanks!

There are some free FEMM programs that will model the magnetron magnet.

The only real question is how many Tesla it puts between the poles, I'd expect.

Thanks, I can look for those.

I don't know the strength. I have an old military Gaussmeter designed for checking the magnets but it has not been calibrated in decades.

Ignoring the earth's field, will a different field strength change the field shape between otherwise fixed poles of a given magnet?

This later work shows using a little pipette as the sample holder, and a few other tricks.

The iron filings idea is great! Maybe some very fine ones and a little thin o-ring of some glue-able material, and two microscope slides would work.
