Electricity and magnetism
Across
- 6. Electrical devices that transfer energy between two or more circuits through electromagnetic induction, used to change the voltage level.
- 7. The production of an electric or magnetic effect by a changing field or magnetization without direct contact
- 8. Induction The process of generating electric current in a conductor by placing it in a changing magnetic field.
- 9. Current The flow of electric charge in only one direction.
- 11. Poles The two ends of a magnet, designated as North and South, where the magnetic field lines emerge and enter, respectively
- 14. The SI unit of electric current
- 15. The SI unit of electric potential difference or voltage
- 19. A material that does not easily allow the flow of heat or electric current.
- 21. Domain A region within a magnetic material in which the magnetization is in a uniform direction.
- 22. An electrical component that limits or regulates the flow of electric current in a circuit.
- 23. Field A region of space where a magnetic force acts on other magnets, electric currents, or moving charged particles
Down
- 1. A temporary magnet made by coiling wire around an iron core and passing an electric current through the wire.
- 2. Difference The difference in electric potential between two points, often referred to as voltage.
- 3. A material that allows heat and electric current to flow through it easily.
- 4. The electric potential difference between two points.
- 5. A device that converts electrical energy into mechanical energy.
- 8. Resistance The total resistance of a combination of resistors in a circuit.
- 10. The SI unit of electrical resistance.
- 12. Field A region around a charged particle or object within which a force would be exerted on other charged particles or objects
- 13. Current The flow of electric charge that periodically reverses direction.
- 16. The rate at which electrical energy is converted or transferred.
- 17. Circuit A circuit in which the components are connected across the same two points, providing multiple paths for the current
- 18. A device that converts mechanical energy into electrical energy.
- 20. Circuit A circuit in which components are connected end-to-end, forming a single path for the current.
