| Conduction | the transfer of heat energy between particles as they collide within a substance or between two objects in contact. |
| Convection | the transfer of heat energy by movement of the heated substance itself, as currents in fluids (liquids and gases). |
| Convection current | a loop of fluid (liquid or gas) caused by uneven heating. |
| Electric circuit | a closed, conducting loop in which electric current can flow continually. |
| Electric current | the flow of electricity in an electric circuit. |
| Electromagnet | a magnet created by current flowing in a wire. |
| Generator | a device that uses a magnetic field to turn mechanical-kinetic energy into electrical energy. |
| Heat transfer | the movement of thermal (heat) energy from one place to another. |
| Magnetic field | a region surrounding a magnet that applies a force (a push or pull) without actually touching an object. |
| Magnetism | the force of attraction or repulsion of magnetic materials. |
| Magnet | an object that exerts a magnetic field. |
| Motor | a device that uses a magnetic field to turn electrical energy into mechanical-kinetic energy. |
| Radiation | the transfer of heat energy through space without particles of matter colliding or moving to transfer the energy. |
| Turbine | a huge wheel that rotates when pushed by water, wind, or steam. |
| Conductor | a material that easily carries heat or electric current. |
| Insulator | a material that is a poor carrier of heat or electric current. |
