Magnetic Field on the Axis of a Circular Current Loop
वृत्ताकार धारा-लूप की अक्ष पर चुंबकीय क्षेत्र
In this Class 12 Physics topic from Moving Charges and Magnetism, students learn how to determine the magnetic field produced by a circular current loop at a point on its axis. The topic applies the Biot–Savart law and the principle of superposition to derive the field expression, explains its direction using the right-hand rule, and examines how the field varies with current, loop radius, and distance from the centre. Special cases such as the field at the centre and at large distances help connect the formula with physical interpretation.
