Mechanism of positive magnetophoresis and negative magnetophoresis. 120 A, Positive magnetophoresis. χ c is larger than χ f in which case the CTCs can be drawn toward the maxima of the nonuniform magnetic field. B, Negative magnetophoresis. When diamagnetic CTCs (χ c ≤ 0) are dispersed in a magnetic medium (χ f > 0), the CTCs are drawn toward the minima of the nonuniform magnetic field
