Across 1. are where the magnetic force exerted by the magnetic is strongest 3. the groups of atoms with aligned magnetic fields 5. which are devices thet use an electromagnet to measure electric current 8. is a temporary magnet made by wrapping a wire coil carrying a current around an iron core 10. a large wheel that rotates when pushed by water, wind, or stream 11. flows only in one direction through a wire 12. a single wire wrapped into a cylindrical wire coil

Down 2. the generation of a current by a changing magnetic field 4. refers to the properties and interaction of magnets 6. exerts a force on other magnets and objects made of magnetic materials 7. which is a device that changes electrical energy into mechanical energy 9. uses electromagnetic induction to transform mechanical energy into electrical energy
