  1. 2. A piece of iron that can attract other iron.
  2. 7. This transformer has more turns on the primary coil than the secondary coil and hence decreases the amplitude of an alternating pd.
  3. 8. A subatomic particle that orbits the nucleus of an atom and contains a negative electrical charge.
  4. 9. A machine that converts electrical energy into mechanical energy.
  5. 12. exhibiting or relating to magnetism.
  6. 15. materials or substances which allow electricity to flow through them.
  7. 17. An instrument for measuring current in amperes.
  8. 18. An electromagnetic induction device that produces electric current by rotating a coil within a stationary magnetic field. It converts mechanical energy to electrical energy.
  9. 19. A soft iron or steel core surrounded by a coil of wire, that temporarily becomes a magnet when an electric current flows through the wire.
  10. 20. A point at either end of a magnetic field where the magnetic force is concentrated on the strongest.
  11. 21. field is the influence of electric currents and magnetic materials.
  12. 23. the production of an electrical or magnetic effect through the influence of a nearby magnet, electrical current, or electrically charged body.
  13. 24. To push away by a physical force.
  14. 25. He discovered the electromagnetic induction.
  15. 26. A device for transferring electric power from one coil of wire to another, by means of electromagnetic induction, for the purpose of transforming one value of voltage to another.

  1. 1. induction is the process whereby a conductor and a magnetic field are moved relative to each other to induce (generate) a current or electromotive force (emf).
  2. 3. a material in which the electron does not flow freely or the atoms of the insulator have tightly bound electrons whose internal electric charges do not flow freely
  3. 4. domain A region in which the magnetic fields of atoms are grouped together and aligned.
  4. 5. One of the four main forces that arises between electrically charged particles causing attraction or repulsion.
  5. 6. a conductor, as a copper wire, wound up in a spiral or other form.
  6. 9. is a mineral found in igneous rockthat has magnetic properties.
  7. 10. producing or tending to produce an electric current.
  8. 11. To pull toward one another; as opposite poles of two magnets pull toward one another.
  9. 13. A movement of electrical charges around a closed path or circuit.
  10. 14. force The attraction or repulsion that arises between electrically charged particles and their motion.
  11. 16. magnet A magnet that retains its magnetism after being removed from a magnetic field.
  12. 22. An instrument for determining direction by means of a freely rotating magnetic needle that indicates magnetic north.
