n= 105/cm outer solenoid
n= 125/cm for inner solenoid.
A) B= uo*n* i -------> 4pi *10^-7* 1050*1.25/ 10^-4= 16.5
mT
B) B= B inner- B outer ----> 34.1-16.5= 17.6
B inner = 4pi *10^-7*1250*2.17/10^-4=34.08 left

Two ideal solenoids of radii ? and 5?, respectively, have ?n turns per meter, and each carries a current of ?. Both currents flow in the same direction. The small‑radius solenoid is placed inside the large-radius solenoid so that their axes of symmetry are parallel and separated by a distance ?=3?. Neglecting any magnetic screening effects, express the magnetic field strength on the axis of the small-radius solenoid analytically in terms of the quantities given and the magnetic permeability of...
