Introduction

Where does electricity come from? Electricity on a large scale is seen in nature as lightning, but lightning is not “harvested” to light buildings, run air conditioning or heaters, or power computers and mobile devices. Instead, electricity has to be generated by converting it from another form of energy.

Generators have three main components–coils of wire, magnetic fields, and motion. The wire or the magnets have to move relative to one another to induce electrons in the wires to move.

In this activity, you will build a simple generator and explore how these variables affect generator performance. It is easy to generate small amounts of electricity, but it can be challenging to generate enough power to light a bulb, turn a motor, or power a house.

Objectives

  • Generate electricity using magnets and coils of wire.
  • Distinguish between direct current and alternating current.
  • Compare generators and motors.
