Manufacture and Application in Self-made Electromagnetic Induction Demonstration Instrument

Abstract

Abstract: In view of the existing in the teaching process of electromagnetic induction experiments cannot very good to demonstrate electromagnetic induction phenomenon, using galvanometer, acrylic board, soft material such as wire, magnetic suction type shaft developed the electromagnetic induction demonstration instrument, achieve qualitative and semi-quantitative demonstration of the purpose of the electromagnetic induction phenomenon, can also be adsorbed on the blackboard or whiteboard for many people to watch at the same time, very good solve the teaching difficulty, to achieve the effect of the combination of theory and experiment.

Key words: Electromagnetic induction, Experiment, Teaching aids
