Question

The diagram shows three equally spaced wires that are perpendicular to the page. The currents are all equal, two being out of the page and one being into the page. 1. Which of the three wires feels the greatest force? (a) a (b) b (c) c (d) a and c (e) they all feel the same force 2. Which of the three wires feels the least force? (a) a (b) b (c) c (d) a and c (e) they all feel the same force Questions 3-6: A current I passes through the wire shown in the figure below. The radius of the semi-circular segment of the wire is R. 3. What is the direction of the magnetic field at A due to the current in the segment PQ? (a) up (b) down (c) left (d) right (e) into the paper (f) out of the paper (g) No direction because the magnetic field is zero. 4. What is the direction of the magnetic field at B due to the current in the segment PQ? (a) up (b) down (c) left (d) right (e) into the paper (f) out of the paper (g) No direction because the magnetic field is zero.
