    ¡¾Abstract¡¿ AIM: In order to investigate different exposure of magnetic field on the learning memory of mice when the product of magnetic field intensity and magnetic exposure time is equal. METHODS: Mice were exposed to magnetic field of different intensities, for different exposure time and with different exposure intervals. Mice were put through a Y labyrinth test every four days to evaluate their learning memory. RESULTS: Exposure time had more effects on the mice¬ð learning memory when the product of magnetic field intensity and magnetic exposure time was equal. The shorter the interval time was, the more effects the magnetic field had on the learning memory of mice. CONCLUSION: The magnetic field gradually acts on the learning memory of mice but the injury can be lessened if there is enough recovery time. ......
