Sample Quizzes QUIZ #6 Physics 132 25 points, 18 minutes SCORE________ (1) The figure shows a current, i, flowing through two halfinfinite wires. Use the law of Biot and Savart to find the magnetic field, B, at the point P indicated in the figure. i You may leave your answer in the form of an integral, so long as it is simplified as much as possible. If you introduce a coordinate system, it must be clearly indicated. d i P (2) Provide the specified direction. (a) The figure shows the motion of electrons in a wire which is near the North pole of a magnet. Direction of the force on the wire? (b) A proton travels at constant velocity in a region containing uniform magnetic and electric fields. Direction of the electric field? N electron flow path of proton B (c) The instantaneous velocity of a proton traveling in a magnetic field is given in the figure. Will the proton circle clockwise or counterclockwise? B
