• 2 FRQ problems, 1 will be doing the electric field lines and second is going to be drawing magnetic field lines
  • 1 question is about earth’s magnetic field lines
  • FRQ Question # 2, draw a horseshoe magnet
  • Generator and motor elements going to be on the test we have to identify
  • Will ask on the test what inductors do
    • Inductors resist current flow change
  • Back EMF questions
  • Tangent Galvinometer -

Demos

  • Dropping a magnet down an aluminum pipe; Magnets underneath repel and above attract therefore it comes down slowly. As magnet is moving it’s creating an induced current in the pipe
    • Eddy currents

Practice

  1. Do the practice questions he put on the board
  2. Review homework
  3. Review demos
