Unit 8 - Sources of the Magnetic Field
This unit continues your introduction to magnetic fields, but this time you learn about magnetic fields can be produced. You'll also learn about the Biot-Savart Law, which despite being fun to say, is not very easy to use. Fortunately, it is not found too often on the AP exam, since most magnetic fields on the exam are produced from simple long current-carrying wires or solenoids. Similarly to Gauss's Law, you'll discover that there is a very helpful analog in magnetism called Ampere's Law.
Completing all lessons in this unit takes approximately 8.5 hours.
