Mechanism of action for cell separation. (a) Cell suspension is loaded into a vertical column placed in a magnetic field. (b) Paramagnetic cells are attracted to the column wall where magnetic field is concentrated due to the circumferentially positioned nickel wire. (c) Non-paramagnetic cells are rinsed out of the column by application of the flow at the bottom inlet to the column.
