Magnetically susceptible particles and apparatuses for mixing the same

An apparatus for manipulating a magnetically susceptible component comprising:

• a cavity for manipulating the magnetically susceptible component with an additional substance, the cavity defining a central axis;
• a first coil disposed circumferentially about the cavity in a first position about the central axis;
• a second coil disposed circumferentially about the cavity in a second position about the central axis;
• a reaction vessel disposed within the cavity;
• a first electrical source connected to the first coil such that in response to a first electrical current passing from the electrical source through the first coil, the first electrical current generates a first individually addressable magnetic field substantially parallel to the central axis;
• and
• a second electrical source connected to the second coil such that in response to a second electrical current passing from the electrical source through the second coil, the second electrical current generates a second individually addressable magnetic field substantially parallel to the central axis;
• wherein
• the first and second magnetic fields define distinct, fluidly connected, reaction volumes within the reaction vessel.
