Experiment 2
Electromagnets: Does the strength of an electromagnet increase with greater current?

Purpose/Hypothesis

In this experiment, you will create an electromagnet and test the effect of varying levels of electric current on the strength of the magnetic field. You will increase the current by adding batteries to the circuitThe complete path of an electric current including the source of electric energy.—the path of the electric current through a wire attached to the terminalsA connection in an electric circuit; usually a connection on a source of electric energy such as a battery. of a source of electric energy. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of...
