1. A downhole magnetic pump system, comprising:
a tube positioned within a wellbore, the wellbore at least partially filled with a fluid;
a conductive wire coil helically wrapped around an outer surface of the tube and configured to generate, in response to an electrical current passing through the conductive wire coil, a magnetic field;
a standing valve assembly positioned within the tube and comprising a first one-way valve, the standing valve assembly comprising a first portion configured to remain stationary within the tube and a second portion configured to axially move towards and away from the first portion;
a travelling valve assembly comprising a second one-way valve and positioned in the tube uphole of the standing valve assembly, the travelling valve assembly axially movable within the tube and configured to travel in an uphole direction in response to the magnetic field and to repetitively cycle between a first position uphole of the standing valve assembly and a second position uphole of the first position in response to the electrical current repetitively switching between a first state and a second state, thereby displacing a portion of the fluid in the uphole direction from a location within the wellbore or the tube downhole of the standing valve assembly to a location within the tube uphole of the travelling valve assembly.
