10. A particle repelling arrangement comprising:
a particle intake chamber having an inlet region in fluid communication with a gas segregation region;
a particle repelling screen comprising a planar array of conductive wires arranged across an internal passageway of the intake chamber, each of the conductive wires spaced apart from adjacent wires to define particle passageways;
a power supply electrically coupled to the conductive wires, the power supply configured to deliver alternating current to the conductive wires,
wherein the alternating current is phase-shifted between adjacent wires, of the conductive wires and the alternating current generates a time-varying magnetic field configured to induce electromagnetic repulsive forces that displace iron-based regolith particles laterally away from the gas segregation region.
 
17. A method for repelling iron-based regolith particles in a particle filtration system, the method comprising:
providing a particle intake chamber in fluid communication with a gas segregation region;
suspending a planar array of conductive wires across an internal passageway of the intake chamber;
delivering alternating current to the conductive wires using a power supply, wherein the alternating current is phase shifted between adjacent wires of the conductive wires;
generating a time-varying magnetic field from the alternating current; and
repelling iron-based dust particles laterally away from the gas segregation region via electromagnetic force generated by the time-varying magnetic field.
