Unformatted text preview: Version PREVIEW – hw12 – Shneidman – (12110) 1 This print-out should have 17 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. Air Core Solenoid 02 001 (part 1 of 3) 10.0 points A 60 mA current is carried by a uniformly wound air-core solenoid with 581 turns as shown in the figure below. The permeability of free space is 1 . 25664 × 10 − 6 N / A 2 . 6 m A 8 . 19 mm 13 . 5 cm Compute the magnetic field inside the solenoid. Correct answer: 0 . 000324492 T. 002 (part 2 of 3) 10.0 points Compute the magnetic flux through each turn. Correct answer: 1 . 70947 × 10 − 8 Wb. 003 (part 3 of 3) 10.0 points Compute the inductance of the solenoid. Correct answer: 0 . 165534 mH. RL Circuit 02 004 (part 1 of 5) 10.0 points A circuit is set up as shown in the figure. L R 1 R 2 E S I 1 I 2 I The switch is closed at t = 0. The current I through the inductor takes the form I = E R x parenleftBig 1- e − t/τ x parenrightBig where R x and τ x are to be determined. Find I immediately after the circuit is closed....
