摘要:
The earliest experiment a student performs when studying electromagnetism is the magnetic field at the center of a flat circular coil carrying an electric current. Later he may study the field at points along the axis of the coil. This paper deals essentially with the measurement of the magnetic field at points along a diameter of the coil, which is not generally attempted. The paper focuses on the usefulness of this laboratory exercise from the standpoints of pedagogy and practical application.
