Unformatted text preview: mcconnell (kam2342) – oldhomework 19 – Turner – (60230) 1 This print-out should have 11 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A cross section of a long solenoid that carries current I is shown. I I (into the page) I (out of the page) r All of the following statements about the magnetic field vector B inside the solenoid are cur- rent EXCEPT 1. The magnitude of bardbl vector B bardbl is proportional to the number of turns of wire per unit length. 2. The magnitude of bardbl vector B bardbl is proportional to the current I . 3. An approximate value for the magnitude of bardbl vector B bardbl may be determined by using Amp` ere’s law. 4. The magnitude of bardbl vector B bardbl is proportional to the distance from the axis of the solenoid. 5. bardbl vector B bardbl is directed to the left. 002 10.0 points A point P is at a distance r from the axis of a very tightly wound, infinitely long solenoid; i.e. , a perfect solenoid....
