Creating a Lunar Magnetosphere

One assumes that a body's speed of rotation might affect the magnetic field it projects. 

Though Luna has a weak magnetic field, introducing a large mass into its orbit might break it from tidal lock (one face always towards its companion).  This might cause increased convection and greater heating of the core.  The resulting magnetosphere will shield the moon from solar radiation which strips it of any potential atmosphere.

This will help in colonization.  Water may be found in the deep.  Drilling equipment can be made from 3D robot printers. Until the moon gets a moon to set it to spin air Everything can be Sent up on the moon tether perhaps.  Domes are sensible for Crop growth.  Biology is key in cultivating a living sky.  Gas production and exchange are predicated on this wing.
