y 4 O X A tightly wound thin wire semi infinite solenoid of radius R and n turns per unit length carries a current I Magnetic field well inside the solenoid is uniform but near the end it fans out Find the magnetic induction vector B in terms of radial and axial components at a point outside the solenoid and at a distance x from the end and a very small distance r from the axis You may denote unit vector in the positive x direction by and unit vector away from the x axis in y z plane radial direction by
