How to Build a Simple Electromagnet

Next Generation Science

This concise animated video demonstrates the step-by-step process of creating a simple electromagnet using everyday materials. It introduces the necessary components—a battery, wire with alligator clips, and a metal nail—and guides viewers through the assembly process, clearly showing how electricity flowing through a coiled wire creates a magnetic field capable of picking up paperclips. The video explores key themes of electricity, magnetism, and circuitry, specifically illustrating the relationship between electric current and magnetic force. It highlights the unique property of electromagnets: they can be turned on and off by connecting or disconnecting the power source, unlike permanent magnets. For educators, this resource serves as an excellent introduction to a hands-on STEM activity or a review of circuit basics. The clean, labeled animations make abstract concepts concrete, and the video ends with an inquiry-based challenge asking how to make the magnet stronger, naturally leading students into experimental design and variable testing.
