THE STRENGTH OF AN ELECTROMAGNET. Christopher Hampton Physics GCSE coursework Class 11L Introduction. The object of this project is to plan and carry out a simple, fair, controlled and safe experiment to determine the factors that control the strength of an electromagnet. I know from previous years work that the strength of an electromagnet is determined by the number of coils of wire used, by the amount of current fed through the wires and that by putting a piece of iron or steel in the middle of the coil that the strength is increased. In this project I will investigate the pattern by which changing the amount of current flowing through the coil will change the strength of the electromagnet. I will need to make the experiment fair, simple, reproducible and safe. I will use the ability of an electromagnet to pick up a metal object as the measure of its strength. A panel...
