### Review Blast: Induced emf (Levels: Intro, APB, APC)

This podcast is a

__very__quick review of Faraday's law of induction, discussing the meaning and calculation of magnetic flux, and the various ways in which a change in flux can happen to lead to induced emf. An added 2 minutes at the end of this podcast reviews how calculations are different in a calculus-based application of Faraday's law.### Review Blast: Magnetic Field & Forces (Levels: Intro, APB, APC)

This podcast is a

__very__quick review of how to perform several different calculations related to magnetic field. (It does NOT review directional aspects of magnetic forces, such as the right-hand rule.) Long straight current-carrying wires are discussed, from the perspective of B-fields they create and how they are affected by external B-fields. The effects of a B-field on a moving charge's motion are also reviewed.### Review Blast: Series & Parallel Circuits (Levels: Intro, APB, APC)

### Ampere's Law (APC)

This podcast introduces Ampere's Law, a powerful formula allowing the calculation of magnetic fields due to currents for certain symmetric situations. Comparisons are made to Gauss' Law in an attempt to remind students of the power of symmetry when calculating fields, and example problems are also included.
