Strength of an Electromagnet Aim and Plan Aim To find out the strength of an electromagnet by changing the number of coils of wire wrapped around it. Prediction I predict that as I increase the number of coils around the electromagnet, the electromagnet will be able to lift increasing amount of weight. I predict that when I have plotted out my results into a graph I will have a straight line, meaning that the weight lifted is directly proportional to the number of coils around the electromagnet. Plan First of all you will need to set up all the apparatus highlighted in blue on page 2. A diagram of how this should be set up is shown below. Now that all the apparatus is correctly set up turn on the power pack and make sure that it is set to 3 volts. Then start with 2 wraps of coil and work your way...
