Unformatted text preview: Name: ______________________ Class: _________________ Date: _________ ID: A 1 quiz4 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. If a proton is released at the equator and falls toward the Earth under the influence of gravity, the magnetic force on the proton will be toward the: a. north. b. south. c. east. d. west. ____ 2. A horizontal wire of length 3.0 m carries a current of 6.0 A and is oriented so that the current direction is 50 ° S of W. The Earth's magnetic field is due north at this point and has a strength of 0.14 × 10 − 4 T. What is the size of the force on the wire? a. 0.28 × 10 − 4 N b. 2.5 × 10 − 4 N c. 1.9 × 10 − 4 N d. 1.6 × 10 − 4 N e. 5.9 × 10 − 4 N ____ 3. A circular loop carrying a current of 1.0 A is oriented in a magnetic field of 0.35 T. The loop has an area of 0.24 m 2 and is mounted on an axis, perpendicular to the magnetic field, which allows the loop to rotate. If the plane of the loop is oriented parallel to the field, what torque is created by the to rotate....
