    摘要： According to one embodiment, a magnetic sensor includes a first sensor part. The first sensor part includes a first magnetic member, a first counter magnetic member, and a first magnetic element. A direction from the first magnetic member toward the first counter magnetic member is along a first direction. The first magnetic element includes one or a plurality of first extension parts. The first extension part includes a first magnetic layer, a first counter magnetic layer, and a first nonmagnetic layer. The first magnetic layer includes a first portion, a first counter portion, and a first middle portion. A direction from the first portion toward the first counter portion is along the first direction. The first middle portion is between the first portion and the first counter portion. The first nonmagnetic layer is between the first counter magnetic layer and at least a portion of the first middle portion.

    摘要： Methods and systems are provided for an oil sensor. In one example, the oil sensor is a system for metallic debris detection, comprising a detection circuit including a first inductor and a second inductor, the second inductor shielded from the external environment, wherein the detection circuit generates an output based on a difference between a first voltage of the first inductor and a second voltage of the second inductor, where the difference indicates a presence of metallic debris within oil.

    摘要： According to one embodiment of the invention, a magnetic sensor includes a first sensor part. The first sensor part includes a first magnetic member, a first counter magnetic member, and a first magnetic element. A direction from the first magnetic member to the first counter magnetic member is along a first direction. The first magnetic element includes one or a plurality of first extending portions. A first portion of the first extending portion overlaps the first magnetic member in a second direction crossing the first direction. A first counter portion of the first extending portion overlaps the first counter magnetic member in the second direction. A first direction length along the first direction of the first extending portion is longer than a third direction length along a third direction of the first extending portion. The third direction crosses a plane including the first direction and the second direction.
