Two similar coils are kept mutually perpendicular such that their centres coincide. At the centre, find the ratio of the magnetic field due to one coil and the resultant magnetic field by both coils, if the same current is flown

The magnetic field at the centre of the current carrying coil

The magnetic field at the centre of the current carrying coil

The magnetic field at the centre of the current carrying coil :

Two similar current loops are placed with their planes mutually perpendicular and centres of both loop lie on the origin. Find the ratio of resultant magnetic field at common centre to the individual magnetic field at common centre.

The magnetic field at the centre of the current carrying coil is
