Instructions Remove the anti-interference bar by sliding sideways against the sharp edge of a vice, work-bench or step. Splice a 6mm diameter line to the thimble. While the Sea Searcher is constructed to withstand heavy lifting duty, the ceramic strontium ferrite core is brittle. It should not be dropped on hard surfaces. Avoid indue impact. 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.

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?

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! Google Classroom teachers can use the Google Classroom button to assign this resource to students.) Vocabulary Independently, electricity and magnetism are both powerful concepts in physics. Electromagnetism is the study of how electricity and magnetism can work together, and electromagnetism is one approach to generating electricity.

Still seems to work though, it found the chimney cap last week and it's now clinging to the Squirrel happily and so are all the tent pegs!

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.

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.
