Across
  1. 2. - : a machine by which mechanical energy is changed into electrical energy.
  2. 4. - an instrument containing a magnetized pointer which shows the direction of magnetic north and from it
  3. 6. current - an electric current that periodically reverses direction and changes its magnitude continuously with tim
  4. 7. - An electric current is a flow of charged particles
  5. 8. - a soft metal core made into a magnet by the passage of electric current through a coil surrounding it
  6. 11. motor,
  7. 14. - a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.
  8. 16. - a coil of wire usually in cylindrical form that when carrying a current acts like a magnet so that a movable core is drawn into the coil when a current flows and that is used especially as a switch or control for a mechanical device
  9. 18. - is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field.
Down
  1. 1. - device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing
  2. 3. - a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a curren
  3. 5. - the angle between the direction a compass needle points (magnetic north) and true north (geographic north) at a specific location on Earth,
  4. 7. - an interaction that occurs between particles with electric charge
  5. 9. - a region around a magnetic material or a moving electric charge within which the force of magnetism acts
  6. 10. - an instrument for detecting and measuring small electric currents.
  7. 12. – attraction or repulsion that arises between electrically charged particles because of their mothion
  8. 13. - an electric current flowing in one direction only
  9. 15. - each of the two points or regions of an artificial or natural magnet to and from which the lines of magnetic force are directed
  10. 17. - a substance or material that allows electricity to flow through it.
