The resulting solenoid is { = 85.0 cm long, and the wire has a diameter of dire = 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 9.20 mT at its center? (The resistivity of copper is 1.70 x 10-8 0. m.) What If? Assume the maximum current the copper wire can safely carry is 22.0 A. (b) What is the maximum magnetic field (in T) in the solenoid? (Enter the magnitude.) (c) What is the maximum power (in W) delivered to the solenoid? w
