But this one is a little smaller version, called an electric keyboard. Demonstrate how you can make your own compass using a magnetized needle. Your support helps wikiHow to create more in-depth illustrated articles and videos and to share our trusted brand of instructional content with millions of people all over the world. http://www.juliantrubin.com/bigten/electric_motor_generator.html, http://www.evilmadscientist.com/2006/how-to-make-the-simplest-electric-motor/, http://www.sciencebuddies.org/science-fair-projects/project_ideas/Elec_p065.shtml#materials, http://www.physicscentral.com/experiment/physicsathome/homopolar-motor.cfm, http://babbledabbledo.com/steam-project-tiny-dancers-homopolar-motor/, http://www.evilmadscientist.com/2006/mhd-i-demonstrate-magnetohydrodynamic-propulsion-in-a-minute/, Creare un Motore con una Batteria, un Filo Metallico e un Magnete, сделать моторчик из батарейки, провода и магнита, hacer un motor con una pila, alambre y un imán, fabriquer un moteur avec une pile, du fil de cuivre et un aimant, consider supporting our work with a contribution to wikiHow. Tape the small magnet to the side of the battery so that it is centered underneath the coil. You don't need any special tools to make a homopolar motor. Copper wires can be insulated easily and current can pass easily from them. Place the needles upright next to the terminals of each battery so that the side of each needle touches one terminal of the battery. I never been seen that!". Tape together four pencils. Exercise caution when working with magnets and electricity. Attach the curved side of the battery firmly to a table or other flat surface using the clay or sticky tack. Current flows from the negative terminal of the battery, through the circuit, and to the positive terminal of the battery. wikiHow marks an article as reader-approved once it receives enough positive feedback. % of people told us that this article helped them. So, a copper or magnet wire copper is your best bet. If you decide to create an account with us in the future, you will need to enable cookies before doing so. Place the free end of the copper wire on the side of the magnet and watch your magnet and screw start to spin! While the principles behind electric current and magnetic fields interacting can be a bit technical, building a basic engine is easy. Stick some modeling clay on either side of the battery so it does not roll away. By using our site, you agree to our. Take 2 small balls of modeling clay and cover the sharp ends of the needle. The exposed wire should be facing the same direction on both sides. For high speed stability, you can make an oval shaped motor. Can I use a thin copper wire for this experiment? If you really can’t stand to see another ad again, then please consider supporting our work with a contribution to wikiHow. Set one neodymium magnet on top of the battery, in the center. This current induces a magnetic field in the coil, which helps explain why the coil spins. The single point of contact between the tip of the screw and the battery serves as a low-friction bearing. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/45\/Build-a-Simple-Electric-Motor-Step-1-Version-2.jpg\/v4-460px-Build-a-Simple-Electric-Motor-Step-1-Version-2.jpg","bigUrl":"\/images\/thumb\/4\/45\/Build-a-Simple-Electric-Motor-Step-1-Version-2.jpg\/aid678230-v4-728px-Build-a-Simple-Electric-Motor-Step-1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
