A long solenoid (n=1200 turns per minute) radius = 2.0 cm has a current of 0.30 A in its winding. A long wire carrying a current of 20 A is parallel to and 1.0 cm to the right of the axis of the solenoid. In unit vector notation, what is the magnetic field at a point on the axis of the solenoid? Assume the axis of the soenoid is perpendicular to the page, and the wires and current wind counter clockwise into the page. Assume the current for the straight wire is out of the page?
