  2. Clicker Question #0 Which famous physicist is responsible for the invention of cartoon characters Beavis and Butthead , as well as King of the Hill (from MTV fame)? A) Albert Einstein – E=Mc2 , Relativity, Brownian motion, etc. etc. B) Matt Groening – Creator of The Simpsons – (liberal arts major) C) Sheldon Cooper – Fictional character on Big Band Theory D) Mike Judge – CORRECT! E) Stephen Billenburg – creator of SpongeBob SquarePants – Marine biologist B A C

  3. Calculate flux through closed surface Small magnetic material such as found in compass can indicate local direction of magnetic field Magnetic Flux through CLOSED surface is ALWAYS zero

  4. Clicker Question #1 What is direction of the magnetic field at points a and b due to the current in the segment of wire? A) a: Out of the page b: into the page B) a: downward b: upward C) a: left b: right D) a: into the page b: into the page E) None of the above B a b A C I

  5. B field from long, straight wire

  6. Clicker Question #2 At which point(s) in the diagram is the NET B field locally pointing INTO the page? A) A B) B C) C D) D E) None of the above D B C B A A C

  7. Clicker Question #3 What is direction of the NET B field at point P due to equal magnitude currents in all 4 wires? down B) up C) left D) right E) None of the above B A C

  8. Clicker Question #4 How many paths have zero enclosed current? 0 B) 1 C) 2 D) 3 E) 4 B A C

  9. B field from Solenoids B A C
