1. A magnetometer-based magnetic material detection device comprising:
a proximal portion, a rigid central body and a flexible and adjustable distal portion, wherein the rigid central body comprises a tube having a circular outer cross-section, a diameter between 2 and 20 mm, and a length between 1 and 60 cm;
two or more magnetometers positioned in or on the distal portion,
a sound emitting device;
a gyroscope in the adjustable distal portion;
an indicator light;
at least one actuator positioned in the proximal portion and connected via a cable, rod, or wire to the distal portion, configured to extend, retract, and move the distal portion angularly away from a central axis defined by the length of the tube of the rigid central body; and
a processor communicatively coupled with the two or more magnetometers, wherein the processor is configured to:
receive magnetic field data from a communication interface of the two or more magnetometers, and
provide a signal to the indicator light and the sound emitting device to turn on the indicator light and provide an audible sound in response to a change in a relative proximity of the two or more magnetometers to a magnetic material based on the magnetic field data, wherein the magnetic material is magnetized.
