Hmm, I'm wondering if you will see some Hall Effect type things happen at
that field strength.

What thickness is the base? What is the element of the metallisation?

I would suggest using the edge mount pins used on ceramic hybrid circuit
bases, to make them into DIP type assemblies. I know people on this list
have pointed at suppliers of these in the past, so if noone answers about
them you may need to dig in the archives.

I am happy with EE. I cannot see anything in the content that I would regard
as not being of engineering interest.
