It has features of convenient operations and notable teaching effect. It is an ideal experimental instrument for advanced physics laboratories. Using this instrument, the following experiments can be conducted: 1. Observe Zeeman effect, and understand atomic magnetic moment and spatial quantization in atomic physics 2. Observe the splitting and polarization of a Mercury atomic spectrum at 546.1 nm 3. Calculate the electron charge-mass ratio based on Zeeman splitting amount 4.
