Problem: The current in a solenoid with 25 turns per centimeter is 0.56 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.
Part A: Find the magnitude of the net magnetic field a radial distance of 0.93 cm from the straight wire.
I need help to solve the above problem and hint: find the magnetic field from the wire and the solenoid separately, and then add them up.
