| Question | Answer |
|---|---|
| What does a generator do? | Uses mechanical energy to produce electrical energy |
| What do generators produce? | Electric currents when the coil of wire is wrapped around an iron core and is rotated near a magnet |
| How does a generator produce electricity? | Are power plants that ________ for homes and businesses. Turbines are huge wheels that rotate when pushed by water (hydroelectricity), wind (windmill), steam (fossil fuels, nuclear, geothermal) |
| What is an electromagnetic? | Is formed when a wire in an electric current is wrapped around in an iron core producing a magnetic field. The strength will increase with additional wraps. |
| What is magnetic field? | Surrounds a magnet and exerts a magnetic force on other magnets |
| What is a simple electric motor? | Turns electrical energy into mechanical energy. It contains an electromagnet that rotates between the poles of a magnet. |
| What do like poles do? | Repel |
| What do unlike poles do? | Attract |
| When an electric current flows through the wire in the electromagnet, a magnetic field is produced, where? | In the coils |
| What is a magnetic domain? | Group of atoms whose fields point in the same direction |
| What is magnetism? | A force of attraction and repulsion of magnetic material (iron, cobalt, nickel). |
| What are the strongest parts of the magnet? | The poles |
