Dynamic filtration system and associated methods

A filter device, comprising:

• a housing having a body portion between a first end portion and a second end portion, the first end portion having a first opening, the second end portion having a second opening, and the body portion defining a cavity between the openings;
• a filter media in the cavity and configured to filter a predetermined substance from a ferrofluid;
• a coil at the body portion and configured to generate a first magnetic field across the body portion;
• a first magnetic plate proximate the first end portion;
• and
• a second magnetic plate proximate the second end portion, wherein the first and second magnetic plates interact to form a second magnetic field across the body portion, and wherein the first and second magnetic fields are configured to drive filtration of the ferrofluid.

A method of filtering fluids, wherein the method comprises:

• receiving a fluid through an inlet of a filter device;
• applying a first magnetic field across a body portion the filter device, wherein the first magnetic field is an electromagnetic field;
• applying a second magnetic field across the body portion of the filter device, wherein the second magnetic field is generated by at least two magnetic plates;
• filtering a substance from the fluid, wherein the fluid is a ferrofluid at the body portion;
• and
• dispelling a filtered fluid through an outlet of the filter device.
