3. Click on “Show Field Meter” toggle on right menu.Move the meter around and observe the magnetic field strengths.Note: themeter reads in G (Gauss) rather then T (Tesla); 1 T = 10 000 GComplete the following statements (4 marks) and do NOT put the meter ontop of the magnet.a) B (total B) gets stronger as you get closer to the magnet and weaker asyou get further from the magnet.b) Bx(x-component of magnetic field) is strongestalong the x-directionc) By(y-component of magnetic field) is strongestalong the y-directiond)(angle of magnetic field), the angle of magnetic field,is measured from the horizontalof the bar magnet...
Data Collection:Pickup Coil (9 marks)Select “Pickup Coil” in top left corner.1.Move the bar magnet left and right THROUGH the coil of wire.Describe the orientationof the magnetic field compared to the coil when themostcurrent is generated.(1 mark)
2.Increase the number of Loops to 3.How does the number of loops affect the current flow: the greaterthe number of loops, thegreaterthe current.(1 mark)
How does Loop Area affect the current flow?Describe the effect and provide a plausibleexplanation.
4. Why is little to no current generated when the bar magnet is moved up and down?
Note: the animations all demonstrate Real Current. Conventional current is the oppositedirectionConventional currentis the opposite of actual electron flow; it is +ve to –ve (use “Right-Hand-Rules”)Real current= actual electron current from –ve to +ve (use “Left-hand-rules”)
