The coil B lies exacity midway between coil A and the point P. The magnetic field at point P due to coils A and B is B1 and B2 respectively.

Two circular coils A and B with their centres lying on the same axis have differents in the same sence. The coil B lies exacity midway between coil A and the point P. The magnetic field at point P due to coils A and B is B1 and B2 respectively.

For the current carrying wire show that the magnetic field at p is
