Electromagnetic induction | The process of creating an electric current in a wire by passing it through a magnetic field. |
Electric force | The push or pull by moving electrons. |
Electromagnetism | The changing of electric fields that cause a magnetic field. |
Magnetic force | The draw of opposite charges towards the different ends of a magnet. |
Magnetic pole | The two ends of a piece of magnetic material where the forces are the strongest. |
Volt | The unit of measurement for electrical potential energy. |
Magnetic field | A region where a magnetic force can be detected. |
Electrical potential energy | The ability to move an electric charge from one point to another. |
Potential difference | The difference in electrical potential energy between two different points. |
Electric current | The rate of flow of electrons in a circuit. |
Solenoid | A coil wire with an electric current in it. |
Ampere | The unit of measurement for current. |
Electromagnet | A strong, temporary magnet made by placing an iron core into a wire coil and passing an electric current through the coil. |
Ohm’s Law | States that potential difference equals electric current times resistance (V=IR). |
Voltage | A difference in electrical potential. |
Ohm | The unit of measurement for resistance. |
Resistance | The opposition to the flow of electrons. |
Electrical power | The rate at which electrical energy is converted to another form of energy. |
Insulator | A material that does not allow heat or electrons to move through it easily. |
Electricity | The flow of electrons. |
Semiconductor | An element or compound that conducts electricity under certain conditions. |
Faraday’s Law | States the relationship between a time-varying magnetic field and an induced electric field. |
Superconductor | An extremely cooled substance that has no electrical resistance and a current can flow indefinitely. |
Electric field | A region surrounding a charged object that exerts a force on anything nearby with an electric charge. |
Conductor | A material that allows electrons to move easily through it. |
