The latest specs you have been give is for a solenoid that will be operated by a 1,000 V power supply. The length of solenoid (in order to work for their application) must be exactly ℓ = 22.0 cm. A cylindrical core will be placed inside the solenoid with a radius of rs = 1.40 cm (luckily, this core has the same permeability of free space as air does). The largest possible magnetic field must be able to be created inside the solenoid, but the thinnest copper wires that the Asia allow you to use are AWG 36 (which corresponds to a wire diameter of dw = 0.127 mm. ).
