Magnetic field of a solenoid and a long straight wire
September 30th, 2022
3. The current in a solenoid with 22 turns per centimeter is 0.50 A. The solenoid has a radius of 1.5 cm. A long, straight wire runs along the axis of the solenoid, carrying a current of 23 A. Find the magnitude of the net magnetic field a radial distance of 0.69 cm from the straight wire.

I don’t understand how the solenoid and the straight wire would add together. I know that the magnetic field that they produce is additive though.
