Electricity & Magnetism

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.

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
