Hall effect is an important physical effect,which can be used in sensor measurement,information processing and other fields.Measuring magnetic induction intensity based on Hall effect is also one of the college physics experiments offered by university of engineering. Starting from the discovery and historical development of Hall effect,it introduces the measuring principles of magnetic induction intensity,carrier density and mobility,further expands and introduces the frontier scientific research — optical field controlling Hall effect and its dynamiceVolution process.The teaching content has gone from simple to profound,from ancient times to the present,which can trigger students’thinking,broaden their horizons,make students having a comprehensive understanding of Hall effect,and lay a foundation for cultivating leading talents who pursue excellence and lead the future.
