This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. The figure represents two long, straight, parallel wires extending in a direction perpendicular to the page. The current in the right wire runs into the page and the current in the left runs out of the page. What is the direction of the magnetic field created by these wires at location a. b and c? (b is midway between the wires.) down, zero, up down, down, up up, up, down up, zero, down up, down, up down, up, down A current is flowing clockwise around a loop placed on your desk. What would be the direction of the resulting magnetic field inside the loop? no magnetic field was generated. upward counterclockwise clockwise downward A long straight wire is aligned north-south and carries current in the northerly direction. What is the direction of the magnetic field created directly above the wire? east west north upward south downward What is the direction of the magnetic field created immediately to the left of the wire? downward north upward south west east If a proton is traveling north directly above the wire, what is the direction of the magnetic force on the proton due to the wire? north east south upward west downward
