core

This video shows you how to make an electromagnet using magnet wire, a ferromagnetic core, and a battery. To view directions for a science project that uses electromagnets, see the “The Strength of an Electromagnet” Project Idea at Science Buddies: http://www.sciencebuddies.org/science-fair-projects/project_ideas/Elec_p035/electricity-electronics/strength-of-an-electromagnet.shtml?from=YouTube The materials to make the electromagnet shown in thisContinue Reading
