Across
  1. 8. a material in which charges do not flow easily because they do not have free flowing electrons.
  2. 10. material a material that can be magnetized because it contains magnetic domains.
  3. 13. a material in which charges can move easily
  4. 15. Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.
  5. 18. flow of electricity through direct contact.
  6. 20. An atom or a group of atoms that has an electric charge.
  7. 21. surrounds every electric charge and exerts force on other electric charges
  8. 24. rapid movement of excess charge from one place to another
  9. 25. transfer of electrons through rubbing
  10. 26. An electric motor is an electrical machine that converts electrical energy into mechanical energy.
  11. 27. a field in a region of space that exerts magnetic forces; a field produced by magnets, by changing electric fields, or by moving charges
Down
  1. 1. a materials ability to allow heat or electric charges to flow
  2. 2. a solenoid with a ferromagnet core (a magnet made by using electricity that can be turned on and off)
  3. 3. the force a magnetic field exerts on a magnet, on a ferromagnetic material, or on a moving electric charge.
  4. 4. a region that has a large number of atoms with aligned magnetic fields
  5. 5. a device that converts mechanical energy into electrical energy by the motion of a coil of wire with respect to a magnetic field
  6. 6. an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge.
  7. 7. a measure of the amount of electrical potential energy an electron flowing in a circuit can gain; measured in volts
  8. 9. the study of behavior of electric charges, including how charge is transferred between objects
  9. 11. the process of generating a current by moving an electrical conductor relative to a magnetic field
  10. 12. a push or pull
  11. 14. attractive or repulsive force exerted by all charged objects on each other.
  12. 16. closed conducting loop in which electric current can flow continually
  13. 17. a measure of how difficult it is for electrons to flow in a material; unit is the ohm.
  14. 19. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
  15. 22. flow of electricity without contact.
  16. 23. the flow of electric charge, measured in amperes
