Conclusionand Recommendation


From this, theresiduals versus the fits are at 0.00. The residual value is -1.0 andthe fitted value is 1.0.

The residuals arealways 0.0 and the percentage from this graph is positive.

There is a higheffect on the treatments AB, and there is not effect in the treatmentA in response C.

In response B,there is an effect in treatment A but no effect in treatment AB withstandardized effect of 12.71

In response A,the percentage versus the residual curve is a linear one. This isbecause there is linearity in the factors being considered andtherefore, they do not fit the line because always residuals shouldbe equal to 0.0

The residualversus order plot is also a clear indication that in response B,there is significance of the data provided and therefore, theanalysis being carried out is important.

This histogramindicates the frequency versus the residuals and as a matter of factthere is both the negative side and the positive side which comes to0.0 when added together showing that there is significance in theexperiment for response A.

This graph showsthat there is no significance in the standardized effect in responseB at α = 0.05.

Conclusionand Recommendation


Magnetism is affected by various factors. The experiment carried outaimed to find out the effects of various factors on the magnetism. Inanswering the question, an experiment was conducted that sought toanswer various questions about the concept of magnetism. The firstquestion that was being addressed was the effect of a number ofwrappings of the wire around the nail on its magnetic strength. Next,the question sought to answer whether the thickness of the wire hadan effect on the power of an electromagnet. Finally, the experimentsought to understand the impact of battery sizes on the strength ofmagnetism. In getting answers to the questions, the experiment wasconducted where variables were determined, and the factors tested. Inthe experiment, it was evident that the number of turns of the wireon the nail was directly proportional to the strength of magnetism.As the experiment was carried out, the results did depict that withthe increase in the number of turns of the wire, there was acorresponding increase in the level of magnetism. The plots doreflect the direct proportionality when it comes to the number ofturns and the subsequent increase in the magnetism. Further, theexperiment carried out did show that with the increase in the levelof voltage, there was a corresponding increase in the level ofelectromagnetism. For the experiment carried out, the increase wasdue to the increase in the number of batteries. An increase inbatteries does reflect an increase of voltage that corresponds to anincrease in the level of electromagnetism. Finally, results of theexperiment did depict that the size of the core may not have asignificant impact on the degree of magnetism.


Findings from the experiment do bring out vital aspects when it comesto the concept of electromagnetism. The experiment does bring outsignificant aspects when it comes to the entire concept ofelectromagnetism. Knowledge of the same can be applied to designingdevices for use. Engineers need to employ skills and knowledge in thefield to come up with designs that are efficient. For example, whencoming up with an electromagnetic device, they need to consider thedifferent factors that would affect the degree of magnetism toachieve the best results. The experiment that was carried out aimedat finding out the various factors influencing magnetism. Knowledgeof the same is a prerequisite in coming up with designs of thatstature. Information derived from the experiment is helpfulspecifically as it offers insight into factors to be considered whendesigning any electromagnetic devices. With knowledge of the same,any variations in the results of the experiment need to be followedby troubleshooting for the changes of the factors that may beaffecting the experiment. Through the same, it will be possible toget designs that are efficient for the work they are meant toexecute. In carrying out the experiment, errors were identified. Theerrors may have been brought about by nuisance factors. Some of theresults derived may have been affected by the same. However, forfuture experimental works, it could be mandatory to conduct theexperiment in a way that avoids the factors that may have affectedthe results. Through the same, more accurate results can be derivedthat can be used to make conclusive decisions.
