Re: magnet falling down tube

It's a potential well whose slopes can be changed.  This allows one do show
the "soft modes" of phase transitions by lowering the sides to make a
shallower well.  One can also show assymetric potential wells which mimic
trapped electrons in  a lattice defect!  Or, you can lower the well until
the particle escapes!   Karl
