Hi all this is my first post.
I would like to see magnetic flux is there anyway I could do this I remember at school many years ago using iron filing. I would like to see the results of magnetic shielding

Well i don't know if this is quite what your looking for but its cool to see a strong magnet dropped down a copper pipe. This is lenzs law .

get some high quality copper and fashion some kind of container and play around lenzs law explains a lot
