According to the Biot -Savart law, the theoretical basis of the distance measured by the magnetic field of loop coils is proposed,and a range finder based on the magnetic field of loop coils is designed and made.The experimental results have about error within 5% when the measuring distance is in the range of 15 ~ 40 cm,which can basically achieve the design effect.
Key words: range finder; Biot-Savart law; magnetic field of loop coil; quick sort
