Across
- 1. a measure of the opposition to current flow in an electrical circuit.
- 7. a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
- 10. a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles
- 13. a substance or device which does not readily conduct electricity.
- 14. substance or material that allows electricity to flow through it
- 15. a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
Down
- 2. the movement of particles, starting at the moment when an external voltage is applied at one of the ends of the conductor
- 3. process of generating electrical current in a conductor by placing the conductor in a changing magnetic field
- 4. a device that converts motion-based power (potential and kinetic energy) or fuel-based power
- 5. basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field
- 6. current through a conductor between two points is directly proportional to the voltage across the two points.
- 8. each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.
- 9. describes the “pressure” that pushes electricity
- 11. any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena
- 12. region in which the magnetic fields of atoms are grouped together and aligned
