Question

PART C: PICKUP COIL
Step 1: Run the PhET sim, “Faraday’s Electromagnetic Lab.” Maximize the window. Click the Pickup Coil tab. You should see a bar magnet, a compass needle grid, and a coil attached to a light bulb.

Step 2: Describe the most effective way of using the magnet and the coil to light the bulb if

1. the coil cannot be moved.

2. the magnet cannot be move.

3. -------) Step 3:. Rank the arrangements and motions shown below from most effective to least effective in terms of lighting the bulb, allowing for ties. For example, if A were most effective, B were least effective, and C and D were equivalent to one another, the ranking would be A > C = D > B.(A=Transverse External) (B=Transverse Internal) (C=Longitudinal Internal) (D=Longitudinal External)   

4. Step 4: Move the bar magnet through the coil and observe the motion of the electrons in the forward arc of the coil loops. Report the correlations of magnet motion and electron motion.  a. Magnet approaches from the left, north pole first; electrons move downward. b. Magnet departs to the right, south end last; electrons move upward. c. Magnet approaches from the right, south pole first; electrons move _?_. d. Magnet departs to the left, north end last; electrons move _?_. e. Magnet approaches from the left, south pole first; electrons move _?_. f. Magnet departs to the right, north end last; electrons move _?_. g. Magnet approaches from the right, north pole first; electrons move _?_. h. Magnet departs to the left, south end last; electrons move _?_.

Answer 1

Answer:

1) Installed and found out the simulation as shown below.

2) a) Coil cannot be moved:

The bar magnet must be oscillated horizontally along the axis of the coil such that it moves towards left and right of the coil, inorder to glow the bulb effectively.

2) b) magnet cannot be moved:

Similarly, now hold the coil and move it in such a way that the magnet is always along its axis and start oscillating it horizontally to make the bulb glow effectively.

3) C>B>A=D

4) c. Magnet approaches from the right, south pole first; electrons move Downwards   
d. Magnet departs to the left, north end last; electrons move Upwards

e. Magnet approaches from the left, south pole first; electrons move Upwards
f. Magnet departs to the right, north end last; electrons move Downwards

g. Magnet approaches from the right, north pole first; electrons move Upwards
h. Magnet departs to the left, south end last; electrons move Downwards
