CHAPTER 8: Ampere's Law
In Chapter 7, you already learnt how to determine the magnetic field intensity using Biot Savart's Law. In Chapter 8, you will learn about Ampere's law to determine the magnetic field intensity. Ampere's law is a simple way to determine the magnetic field intensity compared with the Biot Savart's law. This is comparable with Gauss's law for electrostatic field. However, Ampere's law is only applicable for symmetrical field behavior.
Part 1: Introduction to Ampere's Law
In Part 1, students will be introduced with the concept of Ampere's law based on the current behavior.

Part 2: Filament and Surface Current
Students will learn the analysis of magnetic field intensity for filament current and surface current.

Part 3: Magnetic Flux, flux density, and volume current source
In this part, student will be introduced with the magnetic flux line, magnetic flux density, and the analysis of magnetostatics field intensity due to the volume current source.
Around the current source, there are magnetic field. The magnetic flux is actually a line of magnetic line around the source. The magnetic flux density is a measure of how dense the flux line that pass through the area.

Part 4: Stokes Theorem and Curl
Part 4 discusses the stokes theorem and curl, which is another method to determine the magnetic field intensity other than using Ampere's law. Stokes theorem solve the field integration along the closed surface that is equivalent to the field integration along the closed line.

Part 4(b): Stokes Theorem and Curl (Example & Conclusion)
This part discuss an example related to how to solve the magnetostatics problem using stokes theorem and curl. In the end, you will see that the solution using stokes and curl will give the same answer as solving using ampere's law.
