In the figure below, a long straight wire carries a current of Ią= 5.00 A. A square loop with a side of length 0.250m is placed a distance 0.100 m away from the wire. The square loop carries a current Ip=2.60 A. [0.10m Find the magnitude of the net force on the square loop. 0.25m

Which way would current flow if the silver rod moved to the left?   Clockwise Counterclockwise No Current

Three infinitely long wires running perpendicular to the page carry currents I=250 mA (into the page), I2=100 mA (out of the page), and I =200 mA (out of the page). Suppose that d=0.150 m. What is the net force per unit length on the I wire? (Give the net force in terms of its x and y components, in units of Newtons per meter. Note lo = 4n x 10-7 Tm/A) I3 d a) x component? d

O 180, 90, 180 When using the Biot-Savart law, the angle between 7 and ds is _________ degrees for the left, degrees for the semicircle, and degrees for the right segment of the wire. Use the convention that ds points in the direction of the current. O 180, 90, 0 O 90, 0, 90 O 0.90.0 R O 0, 90, 180 H

Two parallel wires separated by 4.35 cm repel each other with a force per unit length of 1.80 x 104 N/m. The current in one wire is 5.45 A. (a) Find the current in the other wire. (b) Are the currents in the same direction or in opposite directions? O the same direction opposite directions (c) What would happen if the direction of one current were reversed and doubled? This answer has not been graded yet.
