1. A method for fluid filtration, the method comprising:
coupling a transfer pipe between a fluid source and a fluid destination, wherein the transfer pipe defines an interior volume and includes a plurality of electromagnetic filter elements positioned in the interior volume, wherein each of the electromagnetic filter elements comprises a support comb that defines an opening, a solenoid coupled to the support comb, and a plurality of elongated magnetic members arranged in a planar array positioned within the opening of the support comb, wherein each magnetic member comprises a first end and a second end;
energizing the solenoid of each of the electromagnetic filter elements to cause the support comb to generate a magnetic field and to cause the first end of each magnetic member to magnetically couple to the support comb at a corresponding pivot point, wherein each magnetic member is rotatable about the corresponding pivot point; and
flowing a fluid media through the transfer pipe between the fluid source and the fluid destination after energizing the solenoid of each of the electromagnetic filter elements.
