rules works –what does each indicate?
How do magnetic fields get their start - what causes magnetic
fields?
What is the force a magnetic field exerts on a charged
particle? Write down the equation and explain the
direction.
Explain how a solenoid works - how does it produce a magnetic
field?
What are the five major types of magnetic materials? Describe
each briefly.

Pre-Lab Questions
1. How are electric potential and electric field
similar? How are they different?
2. Draw the equipotential lines for a single, positive,
charge.
3. If you were to walk on an equipotential line, how
would your electric potential change over time?
4. What does it mean when equipotential lines are
closer together? What does it mean when they are farther
apart?
5. What direction do electric fields travel?
Explain why Ampere's law for magnetism needs to be
adjusted to include a "displacement current" term and what that
implies about changing electric
field
1) a) Derive a relationship between the electric field (E) and
electric potential (V) knowing that V is defined as the energy per
unit test charge.
b) Based on the above derivation, state an alternate acceptable
unit for (E).
