Jul 8, 2021 · 5. Use a Reed Switch. In the Build a Reed Switch Motor project, students build a simple direct current (DC) motor using an electromagnet and a reed switch and then experiment to explore the effect of voltage on motor speed. The voltage in a DC motor doesn't alternate with time (the way alternating current (AC) does).
Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long. Radio waves are often used to transmit data and have been used for all sorts of applications including radio, satellites, radar, and computer networks. Microwaves. Microwaves are shorter than radio waves with ...
Mar 8, 2022 · The electromagnetic spectrum is the name for the different forms of light that are given off by objects in the Universe. Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays are all types of light, but with different energies! The different types of light have different wavelengths.
Build an Electromagnet Science Projects (9 results) Build an Electromagnet Science Projects. (9 results) 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.
Jan 3, 2023 · heating coil. matches. piece of flat metal or white paper. Set the mirrors around 4 feet apart, with the heating coil placed at the focal point of one of the mirrors. Try placing the piece of metal/paper into the path of the radiation. This will show your students how light is being reflected off of the first mirror.
