Aphysicist is constructing a solenoid. she has a roll of insulated copper wire and a power supply. she winds a single layer of the wire on a tube with a diameter of dsolenoid = 10.0 cm. the resulting solenoid is ℓ = 60.0 cm long, and the wire has a diameter of dwire = 0.100 cm. assume the insulation is very thin, and adjacent turns of the wire are in contact. what power (in w) must be delivered to the solenoid if it is to produce a field of 6.40 mt at its center? (the resistivity of copper is 1.70 ✕ 10−8 ω · m.)
