828 Recognize that electricity can be produced using a magnet and a wire coil.

Key concepts/skills: Level 1: Define key vocabulary. Level 2: Understand how electricity is produced using a magnet and a solenoid. Level 3: Know all material needed to induce an electric current and how the electric current responds to changes in motion of the magnet or wire coil.

Key vocabulary Electricity Electron Solenoid Electromagnetic induction Volt meter

I.Electromagnetic Induction A. The production of an electric current using a solenoid and a magnet. 1. A solenoid has electrons in it but they are not moving 2. When a magnet is placed inside the solenoid, the electrons begin to move which is an electric current 3. If the magnet continues to move, the current continues Recognize that electricity can be produced using a magnet and a wire coil.

II. Development of turbine A. We can now make electricity we just need a way to keep the solenoid or the magnet moving B. Most turbines generate electricity by moving the solenoid between magnets. C. The energy source for a turbine can be gas, coal, wind, water…

III. History A. Electromagnetic induction was discovered by Michael Faraday in He was trying to find the best iron core for an electromagnet. 2. He realized when he placed a magnet in the solenoid he got an electric current. 3. He later learned that if the magnet moved he got a continuous electric current.
