An experiment to see how the voltage passed around an electromagnet effects it. The aim: I want to know how the voltage passed in a coil around an electromagnet effects it. Here is the diagram of the circuit I will use: List of apparatus: Voltmeter, Battery, Paper clips, a nail and wire. Method: Attach apparatus as shown 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: Current Number of paper clips 1.39 3.29 4.41 7.39 9.29 11.59 2 4 7 8 10 11 In this experiment it difficult to learn how to connect and operate a current meter. In this experiment my hypothesis was...
