Two-dimensional images of the artificial magnetic field created by permanent magnets were obtained by means of the Faraday magnetic rotation effect. This provides a convenient and effective means to observe and measure macro-scale magnetic field, as well as lays a base for three-dimensional optical imaging of magnetic field. The magnetic field imaging here can also be considered as a key part of the magnetic rotation geomagnetic field imaging method which we put forward before, and will provide experimental support for this method.
