1. A switchable magnetic filter comprising:
a housing assembly configured to be at least partially disposed within a vessel containing a fluid; and
a magnetic probe rotatably disposed within the housing assembly, the magnetic probe comprising:
a shaft with a first end and a second end opposite the first end, and
a magnetic assembly disposed at the second end, the magnetic assembly including at least one north magnet and at least one south magnet configured to create a north-south magnetic field,
wherein the shaft is disposed within the housing assembly such that the first end extends out of the housing assembly and the shaft is configured to rotate within the housing assembly when the shaft is rotated between an ON position and an OFF position;
wherein, in the ON position, the at least one north magnet and the at least one south magnet are disposed such that the north-south magnetic field flows outside of the housing assembly, and
wherein, in the OFF position, the at least one north magnet and the at least one south magnet are disposed such that the north-south magnetic field is shunted substantially within the housing assembly.
