Firstly we have asked if it was any way to measure and change the voltage given to the magnet, the school has a power supply we can use in order to change it. We have reafirmed our procedure and started the previous investigation. We have created the outline of the written report. we have specified what are our task, hypothesis, materials and procedure and we also have decided which is going to be the format in which the results will be given.
We are going to do three experiments with three different independent variables (the thickness of the iron nucleus, the current/voltage of the battery, number of turn of the cable around the nucleus)
This is how the final electromagnets will look like:
