This Unit gives you an introduction to magnetism and how electric current can give rise to magnetism. You can easily see how these topics are related to the concepts you have studied in the previous units. First, you need to understand how charges move and what happens when they are in motion. Then, you will study how their motion produces a magnetic field. There are 2 Chapters in this unit.
Chapter 4 – Moving Charges and Magnetism: The three introductory topics of this chapter are the concept of the magnetic field, Oersted’s experiment and Biot – Savart law. Other topics include Ampere’s Law, the force between two parallel conductors, and moving coil galvanometer.
Chapter 5 – Magnetism and Matter: In this chapter, you will learn about types of magnets, permanent and electromagnets, solenoid, dipole in a uniform magnetic field, Gauss’s Law, the magnetism of the earth, and how materials have magnetic properties.
CBSE Class 12 Physics Unit 4: Electromagnetic Induction and Alternating Currents
In this Unit, you will understand how electric current and magnetic fields produce a force which is known as Voltage. There are many devices that work on the principle of electromagnetic induction such as electric cookers, transformers and washing machines. There are 2 Chapters in this unit.
Chapter 6 – Electromagnetic Induction: This chapter provides an introduction to the concept of electromagnetic induction. You will learn concepts like Faraday’s laws, Lenz’s Law, induced EMF and current, and Eddy current in this chapter.
Chapter 7 – Alternating Current: In this chapter, you will learn what is alternating current and resonance. A new concept of Power is introduced in this chapter as you will study about power in AC circuits. The working of AC generators and transformers is another important topic from the exam perspective.
CBSE Class 12 Physics Units 5: Electromagnetic Waves
In this Unit, you will study how the electromagnetic waves are produced as electrons oscillate in an electric field. This is a different and interesting concept as you will learn about the electromagnetic spectrum in this unit as well. This chapter will help you score more marks in the competitive exams. There is only 1 Chapter in this unit.
Chapter 8 – Electromagnetic Waves: The chapter begins with the topic of displacement of current and the definition of electromagnetic waves and their properties. You will also learn about the types of electromagnetic waves which includes radio waves, microwaves, infrared, visible, ultraviolet, X-rays, gamma rays.
CBSE Class 12 Physics Unit 6: Optics
Optics is a special branch of Physics that deals with the phenomena of light, its behaviour and properties. In this unit, you will gain a perspective on how light interacts with matter, what is ray optics and wave optics. There are 2 Chapters included in this unit.
Chapter 9 – Ray Optics and Optical Instruments: In this chapter, you will first learn about the phenomenon of reflection and refraction of light. You will also study how light refracts through spherical lenses. Then, you will study prism and the spectrum of light. Then, you will study optical instruments that work upon the phenomenon of reflection and refraction of light.
