Fall 2004 Midterm Exam #2 - Electricity and Magnetism
Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams. Because it was designed for a general physics college course, it would also be appropriate to administer to your high school advanced placement physics classes.

Activity: Slinkies and Magnetic Fields
Your advanced physics class will appreciate this lesson in which they use magnetic field sensors to determine the relationship between the number of turns per meter of a solenoid and the magnetic field produced. The materials for this lesson are costly and ample time is required to prepare for the lesson.

Applications of the Pythagorean Theorem - Magnetism
Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values that make up the magnetic field on a map to observe any patterns.

Where is the True North Pole?
Do you believe in Santa Clause? Or a more practical question might be to ask if you believe in the location of the North Pole. Because of the convection currents in Earth's out core, the magnetic north pole drifts about 55 km per year. As an enrichment when covering Earth's structure, you could assign this as homework and then incorporate a discussion into your class the next day.
