Does it work in real life?
   Following on 
this proposed experiment, using magnets to destabilize 'hot blobs' in ocean water.  Providing a prosthetic magnetosphere to substitute for our weakening field.

Got thinking.  Has this already been tested?  Is there an existing real-life situation where magnets could change the pattern of bacteria?  How about dental implants?  Some of them are held in by magnets.  Do they affect plaque?
INSTANT answer from a 
2005 dental research journal:
... however once again plaque accumulation has found to be increased around magnet retained overdenture abutments.
Googlebooks won't show a long passage, and I'm not sure what an overdenture abutment is, but the connection is clear.  The author was familiar with the problem.  "Once again."
