초음파진동자를 이용한 자계측정방법 연구
Study on the Magnetic Field Measurement Using the Ultrasonic Transducer
초록
A new magnetic field measuring system with induced coil is reported. This system consists of air-cared coil that is forced by the ultrasonic transducer. Induction voltage of coil is proportional to the DC magnetic field and the driving frequency of ultrasonic transducer by the principle of Faraday's law. The experimental measuring system is setup, and the possibility of a new magnetic field sensors is confirmed.
