The+Effect+Of+Voltage+On+Electromagnets

Jonathan R  Cary Academy  ** ABSTRACT **  The purpose of this experiment was to build an electromagnet and find out if different variables affect how it could pick up staples. The hypothesis for this experiment was to find out if the voltage of the battery affected how many staples could be picked up. This experiment was done by using different conductors and batteries to see how many staples each combination could pick up. An extension to the experiment was made by adding another conductor. The new metal nail conductor proved to work better than the long screw conductor, improving the experiment by adding an additional variable. Also, different wire gauges and the number of times the wire was wrapped around the conductor were used as variables. The data was recorded and compared to see which combination of conductors and batteries could pick up the most staples. A scatter plot was made along with a column graph to show the outcomes of the experiment. A dependent relationship was discovered in the data. The results showed that as the voltage was increased, the number of staples picked up also increased. It was shown that an Energizer battery with a metal nail wrapped 15 times in copper 18 gauge wire could pick up 15 staples, more than any other combination.
