41.A linear solenoid is made of copper wire of diameter 0.4mm. It has a length of 10cm, diameter 1cm and 1000 turns. If the two ends of the solenoid is connected to a battery of emf 2V and current is sent through it, determine the magnetic field produced at the midpoint on the axis of the solenoid.
