Center of current carrying circular coil magnetic induction formula

Answer»

Magnetic field on the axis of circular coil carrying current

Magnetic field on the axis of circular coil carrying currentIt is desired to FIND the magnetic field at a point P on the axis of the coil such that OP = r. Consider TWO small current ELEMENTS, each of length DL, located diametrically OPPOSITE to each other at Q and R. Suppose the distance of Q or R from P is x.
