Question

Please answer the following question correctly :

3. Answer the following, assume we are looking down at the solenoid:
a. If the North Pole enters the solenoid first, the field lines point (.......) the
solenoid.
i. The solenoid will (Choose an item). the magnet and induce a field that points
(Choose an item). the solenoid.

b. If the South Pole enters the solenoid first, the field lines point (Choose an item). the
solenoid.
i. The solenoid will (Choose an item). the magnet and induce a field that points
(Choose an item). the solenoid.

c. If the North Pole leave the solenoid first, the field lines point (Choose an item). the
solenoid.
i. The solenoid will (Choose an item). the magnet and induce a field that points
Choose an item. the solenoid.
d. If the South Pole leaves the solenoid first, the field lines point (Choose an item). the
solenoid.
i. The solenoid will (Choose an item). the magnet and induce a field that points
(Choose an item). the solenoid.

e. The solenoid will always (Choose an item). the magnet at the top of the solenoid and
(Choose an item). the magnet after it has passed through.

4. Why is the graph not symmetric, i.e. why is the first peak wider and shorter than the
second? Look at the graph axes.
5. Why is there a section of the graph between the 2 peaks with no induced emf? What does
this physically correspond too?
6. Why are the graphs inverses of each other, that is to say, why does one graph start with
negative voltage while the other begins positive?
