Ryan is experimenting with core materials for an electromagnet. He slides different core materials through a coil of current-carrying wire. Short the core materials based on whether they will or won't increase the strength of rayan's electromagnet.
Since the logic involved behind an electromagnet to work is that the necessary force must be driven by the voltage. The strength of an electromagnet doesn't-depends on what drives the current. The electric current flowing through the wires of electromagnet determines the strength of an electromagnet.
