1. Notes Jan 6, 2015 Essential Question(s) How is electricity produced with a magnet a coil of wire? YOU NEED YOUR SCIENCE BOOK TODAY!!! Tennessee SPI Objective: Recognize that electricity can be produced using a magnet and wire coil. Check for Understanding Create a diagram to explain the relationship between electricity and magnetism. SPI 0807:12.1 Electromagnetic Induction Instructions 1) First click on "View" from the top-menu bar. 2) Then click on "Slide Show" from the drop-down menu. 3) Then use the right-arrow button on your keyboard to advance through this presentation.

2. Note: another name for electrical current is electricity Notes Making Electricity Using Magnets Here is the solenoid (coil of wire) Here is a picture of electromagnetic induction in action  This process is called electromagnetic induction Note: another name for a coil of wire is a solenoid Note: Electromagnetic induction is how most electricity is generated  Magnets and a coil of wire can create electrical current  The magnet has to move through (or around) the coil The coil has to move through (or around) the magnet or See the diagram below  Notice that the bar magnet is moving through the coil of wire SPI 0807:12.1 Electromagnetic Induction Science

3. Quick Review SPI 0807:12.1 Electromagnetic Induction 1) The two pictures below both show electromagnet induction. How would you increase the electrical current? (p439: Fig 2, Letter B) Picture 01 Picture 02 3) Picture 02 shows an electrical generator. Page 439 describes this process in two parts. What are they? 2) Picture 01 shows a bar magnet being pushed through a solenoid. What are the 5 key components of a generator ? (p440: Fig 4) Science

4. Picture 01 Picture 02 Part 1: You must have a magnet and coil of wire Part 2: You must move the magnet through or around the coil… OR …move the coil over or around the magnet Notes The two pictures below both show electromagnet induction. Describe this process in two parts (p439) Science SPI 0807:12.1 Electromagnetic Induction Answers

5. Picture 01 Notes How would you increase the electrical current? (p439: Fig 2, Letter B) Picture 01 shows a bar magnet being pushed through a solenoid. Science SPI 0807:12.1 Electromagnetic Induction Answers
