摘要:

An undergraduate laboratory experiment is described which allows the student to make direct contact with his lecture course. The magnetic field of a circular loop and of a long straight wire is investigated using only a magnetic compass. As a result of this experiment the magnitude of the horizontal component of the Earth's magnetic field is determined.
