Magnetic Depth Of Cut Control

A drill bit, comprising:

• a bit body;
• a plurality of blades disposed on the bit body and having a plurality of cutter pockets formed therein;
• a plurality of fixed cutters secured within the cutter pockets on the blades;
• a housing having a body portion with a bore extending into the body portion, the housing secured within a blade of the plurality of blades;
• a depth of cut (DOC) element positioned at least partially within the bore and having a working face to engage a subterranean formation, the DOC movable within the bore to extend or retract from a first end of the housing;
• a magnet secured within the bore of the housing between the DOC element and a second end of the housing;
• and
• a magnetic fluid disposed within the bore of the housing between the DOC element and the second end of the housing, the magnetic fluid having a viscosity that changes responsive to proximity to the magnet to provide a variable resistance to movement of the DOC element.
