having equal turns and carrying equal currents in same sense are placed co axially such that they subtend the same solid angle at O Let B be the magnetic field at O due to smaller coil X then 2r X Y 1 Magnetic field at O due to larger coil 2B B 2 2 Magnetic field at O due to larger coil 3 Total magnetic field at O is 4 Total magnetic field at O is 3B 2 O 5B 2
