Moving Charges and Magnetism | Class 12 Physics | Magnetic Field on Axis |

In this Class 12 Physics lecture, we derive and understand the Magnetic Field on the Axis of a Current-Carrying Circular Loop from Chapter – Moving Charges and Magnetism.

What’s covered:
• Recap: Magnetic field at center of circular loop
• Derivation of magnetic field at a point on its axis
• Role of θ and symmetry concept
• Final formula B = (μ₀ I R²) / (2(R² + x²)^(3/2))
• CBSE Boards 2026 important questions

Perfect for Class 12 students preparing for CBSE Board Exams 2026.
