After a study, it has been revealed that the circuit used contains so many built-in errors that cannot be helped. These factors are:• Flux being lost on the corners of the magnet; and• Resistance of the wireNevertheless, all that were predicted happened in the experiment. They seem to be accurate to a certain extent, as they all fit in their own patterns.Evaluation This experiment has worked well and has produced sufficient results that produce quite an interesting conclusion. I did not have any unusual and anomalous results.However, the methods used were not in such way that gives the most reliable results, as, the coils were not done in exactly the same way, so the length of the coils inside the magnetic field is not precisely the same in all cases. A mechanical device could be utilized instead of doing it by hand. The results, however, are not strictly and totally accurate, as the circuit itself is not 100% efficient. The resistance inside the wires drains up some of the energy. Some flux of the magnetic field can also be lost through the magnet's shape, for instance – bended wire around the nail at the end. From this, a high expectation cannot be made from such inefficient system because there is no solution to gain total efficiency.Analysing Evidence & Drawing conclusionsTo draw a conclusion from my graph, first of all I would divide it into Three sections: Section A (the bottom), section B (the middle) and section C (the top). This would now make it easier to describe.The first section (A) looks like it does because for the amount of current put in, only a few of the domains had lined up.My second reading that I took was inaccurate, so on my graph I have circledit, and discluded it in the drawing of the curve. The graph then gets steeper (section B), this is because all of the domains are now lining up. As the strength of The current goes up, the strength of the electromagnet goes up directly...
