การวัดสนามแม่เหล็กโดยอาศัยกฎของฟาราเดย์และแสดงผลด้วยคอมพิวเตอร์

Abstract

     This Lrticle involves magnetic field measurement by using the principle of Faraday's law and displaying with computer tbr using in magnetic ceramic tesr laboratory room. This constructed system compose of small 1in motor, ceramic magnet bar, rclay coil, amplifier, rectifier circuit, intedacing circuit and computer. This mcthod can measure the magnetic lield getting the approximate value and can use in laboratory scale only.
