... which will remain the same are the voltage which I will set at 12V and the size of the iron core of the magnet. The investigation will require me to increase the amount of coils surrounding the iron bar. 100 coils will be the number I will use but this will change throughout the experiment. I also plan to see how much weight the electromagnet will hold. The weights which I will use are 10g each and the apparatus has been designed it will consist of a stand and clamp holding the iron core using a piece of iron I will support the weights from it. I hypothesize that as the number of coils increases, so will the strength of the magnet. This is also true with the current. As I increase the current the magnet will become stronger. This will happen because the stronger the current passing through the individual wires, the ...
