1 d d nd ed (7%) Problem 11: A solenoid is created by wrapping a L = 65 m long wire around a hollow tube of diameter D=4.5 cm. The wire diameter is d=0.55 mm. The solenoid wire is then connected to a power supply so that a current of I= 7.5 A flows through the wire. Randomized Variables L= 65 m D=4.5 cm d=0.55mm I=7.5 A & 20 % Part (a) Write an expression for the number of turns, N, in the solenoid. You do not need to take into account the diameter of the wire in this calculation. N= a 0 D Hints: deduction per hint. Hints remaining m Submit B a B k P Hint A d h L 1 7 8 9 45 6 23 1 0 . I give up!
