Two circular coil A and B subtend the same solid angle at point P lying on the axis of the coils. Smaller coil B is midway between A and P. If both coils. Carry the same current in the same senes then find the ratio of the magnetic field of A at `P(B_(A))` to magnetic field of B at `P(B_(B))`.

Two circular coils A and B having n and 2n number of turns have diameters 2d and d. If they carry the same current. A] Which coil produces the maximum magnetic field at the centre ? B] Which coil produces the minimum magnetic field at the centre ?

Two circular coils X and Y, having equal number of turns and carrying currents in the same sense, subtend same solid angle at point O. If the smaller coil X is midway between O and Y and if we represent the magnetic induction due to bigger coil Y at O as B_y and the due to smaller coil X at O as B_x ,then find the ratio B_x//B_y .
