Third Grade, Build an Electromagnet Science Projects (1 result)
Build or improve a device powered by an electromagnet that forms a magnetic field when an electrical current flows through a wire. Add more wires or magnets to test if you can boost the electricity produced.
You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this project,…
