Switch on battery
Attach as many paper clips as possible and record results
Repeat turning up voltage
I will make sure this is a fair test by sure all variables are the same except the voltage.
I will ensure this is a safe by checking all wires are covered in plastic and clearing my desk.
I predict that the higher the current the more paper clips that can be held.
The Results:
In this experiment it difficult to learn how to connect and operate a current meter. In this experiment my hypothesis was correct. I predicted the higher the current the more paper clips it would hold.
New Modular Science: ‘If the current is increased the field becomes stronger, if it is reversed, the field is reversed; and most importantly, if the current is switched off, the field is lost’
From this I can conclude that the results of the experiment I have done are correct and in the bounds of the laws of nature. However some of my results (the results for 7 and 11 volts) seem to fit outside the line on my graph. This may be due to the fact that some of my paper clips were not the same size due to paint and the current may have been taken up by the actual paper clips.
If I was to do the experiment again I would also like to vary the number of turn the wire has around the magnet. In that case I would think the more turns of the wire the stronger the magnet would be.
