Moving Charges n Magnetism :Ampere's Circuital Law :Magnetic Field due to Infinite wire

In this video, we will cover Chapter 4 of Class 12 Physics: Moving Charges and Magnetism. We will deeply understand Ampere's Circuital Law (एम्पियर का परिपथीय नियम), its statement, mathematical expression, and its most important application—deriving the Magnetic Field due to an Infinitely Long Straight Current-Carrying Wire. We have also discussed the Right-Hand Thumb Rule, the graph between Magnetic Field (B) and Distance (r), and what happens when there are 'n' turns. This is a highly scoring topic for your CBSE Board Exams, as well as JEE & NEET preparation. Make sure to take notes and solve the numerical steps along with the video! 🎯 YOUR QUERIES SOLVED IN THIS VIDEO: Ampere's Circuital Law Class 12 Physics Ampere's law statement and derivation in Hindi Magnetic field due to infinite long straight wire Moving charges and magnetism class 12 important topics Line integration of magnetic field formula Application of Ampere's circuital law class 12 B vs r graph for straight current carrying wire Class 12 Physics Chapter 4 notes and derivation JEE Physics Moving Charges and Magnetism NEET 2026 Physics preparation 📢 Don't forget to Like, Share, and Subscribe to The Swastik Academy for more conceptual Physics videos!
