Magnetic field detection apparatus with magnetoresistive effect element and coil
A magnetic field detection apparatus has been granted a patent (Publication Number: US11885835B2) with a unique design comprising a magnetoresistive effect element and a coil with a first tier part and a second tier part. The coil generates an induction magnetic field applied to the magnetoresistive effect element in a specific direction. The apparatus includes multiple conductors arranged in parallel, with the first tier part having more conductors than the second tier part. Additionally, the apparatus features a substrate, nonmagnetic insulators, and specific distances between the magnetoresistive effect element and the tier parts.
Furthermore, the patent includes claims for a current detection apparatus with similar components but designed for detecting current using magnetoresistive effect elements and coils. The apparatus includes a conductive line to generate a second induction magnetic field, along with a controller to adjust the intensity of the first induction magnetic field. The unique design of the apparatus allows for precise detection and cancellation of magnetic fields, showcasing innovation in the field of magnetic field detection and current measurement technology.
