1. A method of using a magnetic field, comprising:
- measuring and storing magnetic field data indicating magnitudes of a magnetic field in different directions at each time by rotating sensors over a space; and
checking whether a disturbance of the magnetic field exists, using curve fitting parameters such as amplitude and offset of at least one of magnetic field trajectories formed by the stored magnetic field data.
