Not normally, as in, when the aluminum is stationary in regards to a magnetic source you can tell no change. But when the aluminum is in motion a noticeable magnetic force becomes apparent. Lenz Law. Check out the MRI MAGIC youtube video about the MRI machine and aluminum block slowly falling over.

Theres also an interesting video up of 2 quickly spinning copper tubes that when a neodymium sphere is placed in between it levitates due to the opposing magnetic charge the spinning copper creates. Very interesting stuff that could possibly be incorporated into something like a Reich CB with the spinning copper tubes pushing the water?
