A long solenoid with 9.07 turns/cm and a radius of 7.04 cm carriesa current of 20.0 mA. A current of 4.56 A exists in a straightconductor located along the central axis of the solenoid.
(a) At what radial distancefrom the axis in centimeters will the direction of the resultingmagnetic field be at 58.1° to the axialdirection?
(b) What is the magnitude of the magnetic field there?
