Unformatted text preview: 9b Field and Force II ConcepTest Field Two straight wires run parallel to each other, each carrying a current in the direction shown below. The two wires experience a force in which direction? force a) toward each other b) away from each other c) there is no force ConcepTest 5.9b Field and Force II ConcepTest Field Two straight wires run parallel to Two each other, each carrying a current in the direction shown below. The two wires experience a force in which direction? force a) toward each other b) away from each other c) there is no force The current in each wire produces a magnetic field that is felt by the current of the other wire. Using the right-hand rule, we find that each wire experiences a force toward the other wire (i.e., an attractive force) when the attractive currents are parallel (as shown). currents Follow-up: What happens when one of the currents is turned off? one ConcepTest 5.10 Current Loop Current a) left What is the direction of the What b) right magnetic field at the center c) zero (point P) of the square loop d) into the page of current? of e) out of the page I P ConcepTest 5.10 Current Loop ConcepTest Current What is the direction of the What magnetic field at the center (point P) of the square loop of current? of Use the right-hand rule for each wire segment to find that each segment has its B field pointing out of the page at point P. out a) left b) right c) zero d) into the page e) out of the page I P...
