New teaching materials of magnet in grade school education have been tried to develop. William Gilbert（1544-1603）published “De Magnete” in 1600. Supplementary examinations of various magnetizations were conducted according to the book. The magnetization processes were also investigated by electron spin resonance (ESR) spectroscopy. Spectroscopic change according to the strength of magnetization was observed. On the bases of these results, some new teaching materials of magnet and magnetization in grade school education were proposed. |
