To demonstrate the large size of the henry unit, a physics professor wants to wind an air-filled solenoid with self-inductance of 1.0 H on the outside of a 15 cm diameter plastic hollow tube using copper wire with a 0.88 mm diameter. The solenoid is to be tightly wound with each turn touching its neighbor (the wire has a thin insulating layer on its surface so the neighboring turns are not in electrical contact).
How long will the plastic tube need to be?
How many kilometers of copper wire will be required? What will be the resistance of this solenoid?
