A long solenoid with 10.0 turns /cm and a radius of 7.00cm carries a current of 20.0 mA. A current of 6.00 A exists in a straight conductorlocated along the central axis of the solenoid.
(a) At what radial distance from the axis will the directionof the resulting magnetic field be at45.0? to the axial direction?
(b) What is the magnitude of the magnetic field there?
