Unformatted text preview: Version 001 HW14 gavrin (25111) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Long Solenoid 001 10.0 points What current is required in the windings of a long solenoid that has 1272 turns uniformly distributed over a length of 0 . 177 m in order to produce inside the solenoid a magnetic field of magnitude 8 . 53 10- 5 T? The permeablity of free space is 1 . 25664 10- 6 T m / A. Correct answer: 9 . 44551 mA. Solenoids 03 002 10.0 points A solenoid of radius 5 . 3 cm is made of a long piece of wire of radius 2 . 47 mm, length 11 . 4 m and resistivity 2 . 28 10- 8 m. Find the magnetic field at the center of the solenoid if the wire is connected to a battery having an emf 27 . 8 V. Correct answer: T. Infinite Sheet of Current A01 003 10.0 points A conductor consists of an infinite number of adjacent wires, each infinitely long and carrying a current I (whose direction is out-of-...
