Asolenoid of radius 2.0 mm contains 100 turns of wire uniformly distributed over a length of 5.0 cm. it is located in air and carries a current of 2.0 a (i) using ampere's law, calculate the magnetic field strength b inside the solenoid 4 marks] 2 marks] magnetic field at a point on the axis of the solenoid, a distance 10 m from its centre. (ii) draw a diagram clearly showing the direction of current flow in the solenoid and the direction of the magnetic field. (iii) use the biot-savart law to determine the magnitude and direction of the hint: at this distance the solenoid can be approzimated by a coil [6 marks] (iv) calculate the self-inductance l of this solenoid.
