A current of 0.1 A flows through a long solenoid. The radius of the solenoid is 2 cm, the linear density of the turns is 10 ^ 3 m ^ -1. The axis of the wire with a current of 2 A coincides with the axis of the solenoid. Find the field strength at a point 1 cm from the axis of the wire, measured along the radius of the solenoid.
