MAGNET SHIELDING

[Rapadura]

So, could Halbach array do this?

[Rapadura]

So? Any guess about what happens when Halbach array attracts a steel ball inside a closed tube, so the ball can't move freely in any direction, but only back or forward in the tube?

[Rapadura]

No guesses?

Rapadura,

why not start doing some experiments? They are cheap and fun to perform, and will contribute to the rest of us.
Trial and error is the only trustworthy way in areas like this, and keep in mind that errors are important information
in all types of research.

I have attached two informative pdf-files about magnetic shielding.

Inside a halbach tube the magnetic flux is uniform. The steel ball is actually being forced all directions at the same time. There is no sticky spots. However, the tube is a finite thing that will pull the steel ball towards the walls if the steel ball is not in center of the tube. Because the magnets will find the ball as a short cut to close the flux loop.
