You are working at a company that manufactures solenoids for industrial and research use. A client has ordered a solenoid that will be operated by a 1 000-V power supply and must be of length ,l = 25.0 cm. A cylindrical experimental package of radius rs = 1.00 cm must fit inside the solenoid. The client wants the largest possible magnetic field inside the solenoid. The thinnest copper wires allowed by your company are AWG 36, which corresponds to a wire diameter of dw = 0.127 mm. You determine the maximum magnitude of magnetic field that can be created in the solenoid to report to the client.
