Biot-Savart and Ampere's Laws - Review for AP Physics C: Electricity and Magnetism

The video reviews the Biot Savart Law and Ampére's Law, focusing on their applications in determining magnetic fields. It explains the Biot Savart Law's role in calculating magnetic fields around current-carrying wires and introduces the right-hand rule for direction. The alternate right-hand rule is also discussed. Ampére's Law is presented as a tool for calculating magnetic fields in symmetric situations, such as solenoids, with a comparison to Gauss's Law. The video concludes with a derivation of the magnetic field inside a solenoid.
