Electric current is supplied to the coil in opposite directions, depending on the state of switches operated at times T0, for a first direction, and T5, for a reverse current direction. A voltmeter measures voltages across the coil, namely at least V1 at time T1, after T0, and V2 at time T2, after T5, with T1−T0=T2−T5=predetermined ΔT. A processor indicates V1−V2, the magnitude and sign of which indicate the strength and direction of the earth's magnetic field respectively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compass including magnetic field sensor","description":"A compass includes a magnetic sensing element in the form of a coil surrounding magnetic material.
