Magnetism and Electromagnetic Induction Overview — AP Physics 2
1. Unit at a Glance
This unit builds from foundational magnetic properties to advanced induction concepts. You will first learn how magnetic fields are created by currents, then explore how magnetic fields exert forces on moving charges and wires. We then develop the core laws of electromagnetic induction before applying these concepts to real magnetic systems.
The unifying theme of this unit is the deep connection between electricity and magnetism, which underpins all modern electromagnetic technology and prepares you for the study of electromagnetic waves in later units.
Common Pitfalls
Why: Using the wrong rule leads to consistent incorrect direction predictions.
Why: Failing to account for the opposing nature of induced current leads to wrong direction and sign errors.
