Electromagnetism is the study of how electricity and magnetism can work together, and electromagnetism is one approach to generating electricity.Inflatable Kayaks Stand Up Paddle Board (SUP) Oars & Paddles Kayak Paddles & Accessories All Boats & Kayaks Inflatable Boats & Tenders Seago Inflatable Tenders Waveline/WavEco Inflatable Tenders Talamex Inflatable Tenders

An electric generator reverses the process used by an electric motor and converts mechanical energy into electrical energy. (A motor converts electrical energy into mechanical energy.) These experiments involve making and testing an electric generator.

Electric motors use a magnet's ability to attract and repel to create motion. Simple electromagnetic motors help students visualize the relationship between a magnet, its invisible magnetic field, and the objects it interacts with. A simple motor also reinforces the importance of closed circuits. After exploring simple motors, students can learn what happens when an electric motor runs in reverse as a generator. Teaching students about electromagnetism helps them synthesize what they know about magnets and electricity to see how they can work together. The resources below enable hands-on exploration of electromagnetism, electric motors, and electric generators. These experiments are closely related to experiments that teach about electricity, but in these activities, magnetic fields play an important role in converting electrical energy into mechanical energy or generating electric current.

After building the generator, students test with two different configurations of the permanent magnets. Questions: How does the configuration of permanent magnets affect when and how much electricity is generated? How can changes in the magnetic field help maximize the efficiency of the generator?Anodes Sterndrive and Saildrive Anodes Hull and Trim Tab Anodes Propeller and Shaft Anodes Bow and Stern Thruster Anodes Steering & Bow Thrusters Outboard Engine Steering Kits Up To 55hp Outboard Engine Steering Kits Up To 150hp Steering Helms & Steering Wheels Steering Cables & Accessories More Steering & Bow Thrusters The Electricity, Magnetism, & Electromagnetism Tutorial resource is a good place to start when introducing electromagnetism to students. For older students, the resource can be a helpful refresher. The video above offers an overview of magnets and electromagnets. ( Tip!

The free STEM lessons and activities below cover permanent and temporary magnets, electromagnets, ferromagnetic materials, magnetic fields, and alternating and direct current. In these activities, students will learn about the Lorentz force, Faraday's law of magnetic induction, the parts of a motor or a generator, Newton's third law of motion, homopolar motors, and the role open and closed circuits play in electromagnetic devices. Mine is in the boat at the moment, but I seem to remember they have a keep plate on the bottom which you take off. They are quite powerful for their size.
