A long solenoid with 10 turns per centimeter and a radius of 7 cm located in vacuum carries a current of 20 mA. A straight conductor positioned along the axis of the solenoid carries a current of 6 A At what distance from the axis of the solenoid does the vector of the total B‑field form an angle of 45° with the axis of the straight conductor? What is the magnitude of the B‑field at this position?
