EMT - CHAPTER 7 - BIOT SAVART'S LAW (Teaching Videos)

Chapter 7 is the beginning of magnetostatics. You already learnt about electrostatic field and their properties. Electrostatic field produced by static charge. However, when the charge started moving with constant velocity, it become direct current, and direct current is the source of magnetostatics field.

In Part 1, you will be introduced with current elements. The Magnetic field intensity can be produced by different current elements such as filament current current, surface current element, and volume current element. Here, we will initially introduced with the three different current elements.

For Part 2, you will be introduced with Filament Current Element. Filament current elements can produces magnetic field intensity around it. Using Biot Savart's law, we can find the magnitude and direction of the magnetic field around the filament current.

For Part 2, you already learnt about Filament Current Element. Filament current elements can produces magnetic field intensity around it. Using Biot Savart's law, we can find the magnitude and direction of the magnetic field around the filament current.

In Part 3 here, you will see how to determine the Magnetic Field Intensity for filament current elements using Biot Savart's Law.

For Part 4, you will see the analysis of magnetic field intensity produced by circular loop filament current using Biot savart's Law.

Part 5 shows the analysis of magnetic field intensity produced by Solenoid current using Biot savart's Law. Solenoid is a device constructed by having wire wound with many number of turns.

You already learnt from Part 1 - 5 about the current elements that contributes to magnetostatics field. To strength your understanding of this topic, please do this homework as you exercise.
