Han Jing-bo · Physics Experimentation · 2008
Several improvements on a Lenz law demonstration instrument are introduced,and the advantages and disadvantages are analyzed.In order to solve problems caused by the eddy current in the demonstration experiment,copper wire loops are used instead of aluminum loop.The operating skills of teachers and students are increased and the innovating ability of students is cultivated during the process of improving the device.They also enjoy the happiness of success.At the same time,the device can make up the lack of demonstration device in rural areas.
