  1. Electricity and Magnetis Goal 4 Physical Science Study Guide

  2. Goal 4 • Static electricity • Positively • Negatively • Repel, Attract • Conduction • High , Low • Friction • Induction • Open

  3. Goal 4 • 10. Closed • 11a. 3/6=0.5 A • 11b. 1200Ωx0.2=240V • 12a. 29 x 120 = 3480W • 12b. 320/120=0.625A V I R P IV

  4. Goal 4 • 12c. 75/120=0.625 A • 13. Series • 14. Parallel • 15. Least resistance • 16. Inversely • 17a. Length of wire-longer more resistance • 17b. Width of wire-thin more resistance • 17c. Temperature-Higher more resistance • 18. Directly

  5. Goal 4 • 19. Iron, Cobalt, Nickel • 20. Aligned (magnetic fields move from north to south poles) • 21. repel, attract • 22. ADD • 3 things that affect the strength of an electromagnet: # of coils increases magnetism • Amount of current, higher current, higher magnetism • Core Material
