... ne more coil on to the piece iron and turn the power on. Then do the same thing as before except that I change the number of coil of wire by increasing the number by one at the time until it reaches ten coils I stop. After that I repeat all of the experiment again in order to get the average results for each of the experiment. Planning Factors that will be included in the experiment * The frequencies of the current that will be vary when it is being tested. It will be vary every 10 Hz starting from 0 Hz to 100 Hz. * The current will be varying from the power supply. The current will be 0.25A, 0.5A, 0.9A, 0.11A and 0.31A. * Number of coil of the green wire will be change from 1 coil to 10 coils. Prediction What I have predicted the result will be is that for the change in voltage the amount of EMF produced will be proportional to the change of the voltage. For the change in the number of coils I predicted that the change in number of coils would be proportional to the amount of EMF produced and for the change in frequency of the current I predicted that as the frequency increased the amount of EMF produce ...
