1 Exam 2 Fall 2014 Section instructor Section number Last/First name Last 3 Digits of Student ID Number: Show all work. Show all formulas used for each problem prior to substitution of numbers. Label diagrams and include appropriate units for your answers. You may use an alphanumeric calculator during the exam as long as you do not program any formulas into memory. By using an alphanumeric calculator you agree to allow us to check its memory during the exam. Simple scientific calculators are always OK! A Formula Sheet Is Attached To The Back Of This Examination Be Prepared to Show your Student ID Card Score on each problem: 1. (20) 2. (20) 3. (20) 4. (20) Total Score (out of 80 pts)

2 2 1. Conceptual Questions (20 point) Put a circle around the letter that you think is the best answer (4pts) Two loops of wire are moving in the vicinity of a very long straight wire carrying a steady current. Find the direction of the induced current in each loop. (CW stands for clockwise direction; CCW counterclockwise) Loop A: A) CW B) CCW C) No current Loop B: A) CW B) CCW C) No current 1.2.(4pts) The three loops of wire shown in the figure are all subject to the same uniform magnetic field that does not vary with time. Loop 1 oscillates back and forth as the bob in a pendulum, loop 2 rotates about a vertical axis, and loop 3 oscillates up and down at the end of a spring. Which loop, or loops, will have an induced emf? A) Loop 1 B) Loop 2 C) Loop 3 D) Loops 1 and 3 E) Loops 2 and 3

3 (4pts) Magnetic flux depends upon A) the magnetic field B) the orientation of the area with respect to the field C) the area involved D) all of the above E) none of the above 1.4. (4pts) Figure shows a small positive charge q moving toward a long current-carrying wire. Which of the arrows labeled A to D correctly represents the direction of the magnetic force applied on the charge A) A B) B C) C D) D E) The force points in a direction perpendicular to the plane of the figure (4pts) A charged particle is injected into a uniform magnetic field such that its velocity vector is perpendicular to the magnetic field vector. Ignoring the particle's weight, the particle will A) move in a straight line B) follow a spiral path C) move along a parabolic path D) move along a hyperbolic path E) follow a circular path

4 4 Problem 2. (20 pts) Calculate the currents in each resistor. (Writing the equations (15 pts); solving them (5pts)).

5 5 Problem 3. (20 pts) The figure shows a cross section of a hollow cylindrical conductor of radii a and b, carrying a uniformly distributed current I (direction is out of the page). Determine the magnetic field at a distance r from the axis for: (a) (6pts) r < b; (b) (8pts) b < r <a; (c) (6pts) r>a (Show amperian loops; at least for one of the cases (a, b, or c) show how you handle a linear integral)

6 6 Problem 4. (20 pts) A conducting rod whose length is 25 cm is placed on a U-shaped metal wire that has a resistance R of 8 Ω as shown in the figure. The wire and the rod are in the plane of the paper. A constant magnetic field of strength 0.4 T is applied perpendicular and into the paper. An applied force moves the rod to the right with a constant speed of 6 m/s. (a) What is the magnitude of the induced emf in the wire? (b) What is the magnitude and direction of the induced current in the wire.
