Wendy
Instructions:
Using a pencil, complete the following notes as you work through the related lessons. Show ALL
work as is explained in the lessons. You are required to have this package completed BEFORE
you write your unit test. Do your best and ask questions if you don’t understand anything!
Electromagnetism:
1. Provide a brief summary of the discovery of magnetism and the understanding of magnets.

stuck to a magnetite rock
2. Draw the field lines that surrounds a single bar magnet. State the rules that govern how the field
lines are spaced and directed. (note that the direction the compass in the direction as indicated by
the red side of the compass needle)
Rules:
1. the field lines go from north to south
2. lines never intersect
3. more dense lines =
stronger field
Magnetic Fields:
•
1. Define a “force field.” You could even reference Star Wars as you explain this.

2. There are two other phenomena that have force fields, besides magnetism (HINT: you’ve studied
them both in this course). Compare their equations, directions, and the main components
affecting their strength.
Electric Gravity
E--

mg
3. What is the difference between permanent magnets and electromagnets? Provide details and
examples of each.

iron
4. We traditionally use a compass to navigate. We “know” that the compass points north and we
navigate according to this fact. Explain what you see and describe the paradox. Discuss what is
truly happening when we navigate with a traditional compass (where is it pointing?).
Magnetic North Pole
•
The Needle points at the South ,
which
North Pole
is the
magnetic
•
Magnetic South Pole
•
5. What causes a magnetic field in an electromagnet and a bar magnet? Describe how they are both;
ultimately, caused by the same thing (some Internet research may be required).
6. Sketch the current and field lines surrounding the following magnets. Draw arrows on the
compasses to show which way they’d be pointing.

7. Complete the diagrams below by adding in the compass arrows based on the one compass given.
Then determine which end of the wire is positive and which must be negative (label)
8. Describe the RHR (right-hand-rule) using a sketch and comments, for both a single wire and a
solenoid.

10. Using your knowledge of magnetism and the right hand rule, determine whether the solenoids (coils)
will attract or repel each other. Be sure to draw in the field lines and label the North and South
poles.
