One concept is to find a water soluble chelating agent that can bind only three metal ions with the fourth chelating ligand
being polar but unable to bind well with a metallic atom. This would result in a molecule that would have an imbalance of
paramagnetic transitional metals on one portion of the chelate and the other ligand not having a bound metal ion.
The molecule would inherently be lopsided in terms of magnetic quality
Think of a tetrahedron with three of the base vertices being iron and the top of this pyramidal structure having a polar charge.
An
electrostatic charge orients the molecule with the paramagnetic atoms being constrained the chelate cage.
A
magnetic force is then applied which affects the bound iron atoms.

"Hamaguchi et al. observed magnetic ionic liquids by introducing FeCl4 to the anion part to form
1-butyl-3-methylimidazolium tetrachloroferrate, (Bmim)FeCl4.1,2) A magnetic fluid is a liquid with
magnetic properties. However, a conventional magnetic fluid contains volatile solvents. It causes a
change of viscosity and phase separation by cohesion/precipitation. On the other hand,
the magnetic
ionic liquid is a highly stable and non-volatile liquid. Moreover, this magnetic ionic
liquid responds to a magnetic field by a permanent magnet, because it shows large magnetic
susceptibility at room temperature."---------------------------------------------------------------------------------------------------------------------------
I propose that the magnetic susceptibility can be further increased by the addition of nano-particles in the 10 to 100 nM size range
that are used in the ferrofluid technologies. In this situation the carrier fluid has a magnetic component to it as
would be good choice for the Series 6 trials
The
ionic/aqueous ferrofluids will be addressed in Series 7 trials..
Also since the images by seem to indicate that iron atoms are closely held by ionic forces and are not separated from the
structure by applied magnetic forces. However the magnetic force is sufficient to move the entire chelate structure jm
