I thought that only the mass driver bucket had to be metalic
and that one could use induced electromagnetic force to create
a magnetic field in the bucket.  No need for iron...  Was I
mistaken?  I remember a demonstration from high school physics
where a coil induced a magnetic field in an iron rod.  Aluminum
rings stacked on the iron rod would head for the ceiling.
Required a fluctuating magnetic field though.
