Magnetic Field Due to Long Straight Wire | Class 12 Physics | Moving Charges & Magnetism

In this Class 12 Physics video, we cover a key topic from Chapter 4: Moving Charges and Magnetism. We derive the formula for the magnetic field produced by an infinitely long straight conductor carrying a steady current. Key concepts covered: Application of the Biot-Savart Law. The derivation of the final formula: B = \frac{\mu_{0}I}{2\pi r} Understanding the factors affecting the magnetic field strength. Determining the direction of the magnetic field using the Right-Hand Grip Rule. This tutorial is essential for CBSE, NCERT, and competitive exam preparation like JEE and NEET.
