Chapter 4 of Class 12 Physics, Moving Charges and Magnetism, dives deep into the world of magnetic fields and their interaction with moving electric charges. The chapter introduces essential topics like the magnetic force on a moving charge, Ampere’s law, magnetic field due to current-carrying conductors, and the Biot-Savart law. These concepts are foundational for understanding how magnetic fields influence electrical currents and are vital in modern-day applications like motors, generators, and transformers.

This chapter is crucial for understanding electromagnetic theory, which has direct applications in devices such as electric motors, transformers, and even medical technologies like MRI scanners. This article will break down the essential concepts of Moving Charges and Magnetism, making it easier for you to grasp and apply them to both theoretical and numerical problems. Additionally, I’ll provide you with a direct link to download the NCERT PDF for this chapter, so you can study efficiently.

Key Concepts in Moving Charges and Magnetism

Class 12 Physics Chapter 4 covers the following fundamental concepts:

Magnetic Field and Force:
- The magnetic force on a moving charge
- Formulae for magnetic force
- Right-hand rule for direction of force
- Force on a current-carrying conductor
- Concept of torque in a magnetic field
Magnetic Field due to a Current-Carrying Conductor:
- Magnetic field around a straight conductor
- Magnetic field due to a circular loop of current
- Solenoid and its magnetic field
- Ampere’s law and its applications
Biot-Savart Law:
- Derivation of Biot-Savart law
- Application of the law to calculate magnetic fields
- Magnetic field due to a current-carrying wire
Magnetic Properties of Materials:

NCERT Class 10 Math Chapter 14 प्रायिकता (Probability) introduces students to the concept of chance and likelihood of events. In this chapter, students learn how to calculate the probability of simple events using the formula P(E) = Number of favourable outcomes ÷ Total number of outcomes. The chapter deals with real-life examples like tossing a coin, rolling a dice, or drawing cards, which makes the subject more interesting and practical. Since probability questions are common in board exams and are generally considered easy, this chapter is highly important for scoring well.

I am writing about this topic because probability is not only an important part of the Class 10 syllabus but also a concept that students will use in higher studies and real life. From predicting weather conditions to calculating risks in business, probability plays a key role. Many students initially find it confusing, but NCERT presents it in a simple and easy-to-understand manner. By practising from the NCERT book, students can build a strong foundation and develop confidence in solving probability problems. Having the PDF makes it easier for learners to access the chapter anytime, revise formulas, and attempt practice questions before exams.
