Experiment with Magnets and Motors Science Projects (15 results)

In this science project, you will build what might be the world's simplest motor. It has just four basic parts: magnets, a battery, a screwdriver, and a short piece of wire. It takes only minutes to assemble, but it provides a wonderful device to explore how electricity and magnetism combine to produce a fast-spinning motor. Read more

What happens if you hold a magnet next to water? You might think that water is not affected by magnetism, but in fact, the water is slightly repelled. Believe it or not, if the magnet is strong enough, you can use this effect to levitate objects that contain water, including insects and even small frogs! In this science project, you will learn about diamagnetism. Materials that are repelled by both poles of a magnet are called diamagnetic. The magnets you will use are not strong enough to float… Read more

Motors are used in many things you find around your house, like your refrigerator, coffee maker, and even a lawn mower. In this electronics science fair project, you will get to build a simple motor, using a kit, and then test how the number of batteries (amount of voltage) used to power the motor affects its performance.

An electric current produces a magnetic field. You can take advantage of this fact to make a simple apparatus to test the electrical conductivity of various materials, including both solids and liquids. The detector consists of a coil of wire, with a magnetic compass inside it. You connect one end of the coil to a D-cell battery. The other end of the coil is connected to whatever material you are testing, and the material, in turn, is connected to the other end of the D-cell. In other… Read more

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. Read more
