This is because from Fig 1. 4, 1. 5 and 1. 6 the results show that there is hardly any significant change in the results. However when the solenoid is placed on the right hand side of iron core there is a slight change of 0.

0002 grams of iron filing collected in comparison to the other two positions (middle and left hand side) but this change is quite insignificant. The voltage also remained the same throughout all the nine experiments (as expected) and was measured with a voltmeter since the power supply was set to 3 volts at all times and therefore was anyway a constant (the voltage was measured with a voltmeter eventhough it wasn’t really needed because the power supply was set to 3V). From the results that were obtained for current a conclusion could not be drawn and there for it is difficult to say anything about current in this specific experiment.

There was one set of results (Fig 1. 4, Right hand side position) that was slightly anomalic (0. 0002g) in comparison to the other results but this will be later on analysed in the evaluation. Weber suppressed dciana’s functionalism . I can conclude by saying that my hypothesis was correct since the results (except for current in Amps) received were as I thought they would be. dciana, please do not redistribute this project.

As in most of the experiments there are always a few improvements that can be made to get even better and more reliable results than the ones obtained from the previous one. The first factor in this experiment that could be improved is that of the ammeter readings, since the ammeter that was used was first of all not digital and only went up to 2 amps (however for this experiment we were looking at a greater current than just 2 amps).

So either a potentiometer /variable resistor (to decrease the current) or a digital ammeter could be used, which would display higher currents than just 2 amps. The second factor in this experiment that could be improved would be that of the coiling of the wire around the metal coil because the wires were supposed to be tightly wrapped around the coil so there would be a 1 mm space between the wires (the solenoid was made up of 25 loops of insulated wire).

Not following this factor was the reason for slight anomalic results (see Fig 1. 5) between the positions middle and right plus left and right because for the two sides (middle and left) one partner looped the wires around the metal core and for the other side (right) the second partner looped the wires around (obviously differently than the first partner) the metal core. The third factor that could be improved in this experiment would be that of the tape (to keep the solenoid in place), since this could have been measured (e. g.

4cm per experiment) because in this experiment the tape was not measured and therefore became an uncontrolled variable. It is very difficult to say whether the last position’s (right) results were anomalic because of the third factor or simply because the balance might have been reset incorrectly since the difference between the right hand side position and the other two positions (middle and left) was just 0. 0002 grams. If this experiment was to be done again then it would a good idea to have a closer look at the three factors mentioned above.cogc gcr segcgcw orgc gck ingc fogc gc;

Altogether this was a successful experiment because not only was the aim met but also the hypothesis was proved to be correct and most of the results were also reliable except for perhaps that one set mentioned above. coce cer sececew orce cek ince foce ce; Bibliography: fo ea fGCSE Double Science Physics Book – The Revision Guideor ea more dissertation ea Do ea not ea redistribute mqR8F15 I would like to acknowledge this book in helping me with scientific evidentiary support.
