Concept of Electromagnetic
Students learned the concept of Electromagnetic induction, through trying a number of experiments.
To test the effect of the “powered-up” copper wires on the compass (tested in two situations: with and without turning the power up)
Students tried the experiments using copper wires (powered up) to attract the paper clips in different conditions:
With and without electricity
Different number of batteries (2 / 4 )
Number of turns of the copper wires ( 30 and 90) using 2 batteries
Number of turns of the copper wires ( 30 and 90) using 4 batteries
Open questions: if they need to attract more clips, what would they do?
