UNIQUE FEATURETime and cost-saving compared to the traditional experiment. The experiment can be easily manipulate and may be repeat many times without worrying the equipments.Different variable can be tested, enable us to predict how the current will change when the conditions are varied like when the magnet moves through the different size of coil at different speeds. Show accurate and consistent result at all time.Allow every student to participate for this experiment easily and can see the result significantly. Provoke their understanding more easily as student have more time to compare and discuss their result with one another for analysis of this experiment.
