1. A downhole tool comprising:
a position sensor comprising a first set of magnets and an internal slider;
a valve magnet assembly comprising a second set of magnets magnetically couplable to the first set of magnets, the second set of magnets being positionable circumferentially around an outer diameter of the position sensor, the valve magnet assembly configured to move in response to a fluid valve, and the valve magnet assembly configured to cause the internal slider of the position sensor to move in response to movement of the valve magnet assembly, wherein the second set of magnets is embedded in a housing and positionable circumferentially at least at opposing sides of the outer diameter of the position sensor relative to a central longitudinal axis of the housing;
the fluid valve for controlling an amount of fluid production from a wellbore;
a mandrel couplable to the fluid valve, wherein the mandrel is configured to move in response to adjustments to the fluid valve;
a bracket couplable to the mandrel, wherein the bracket is configured to move in response to movement of the mandrel; and
a slider couplable to the bracket and the valve magnet assembly, wherein the slider is configured to move in response to the bracket and is further configured to cause movement of the valve magnet assembly, and wherein the slider is configured to move radially relative to the bracket.
