show work please i need help , not sure if im correct?

Question 4 (1 points) (#714823) {Magnetic Force on/by Wires) A straight wire, labeled as Wire A, lies horizontally on a tabletop and is oriented to run north-south. A conventional current of 1.0 amperes runs in the wire directed towards the north. A second wire, labeled as Wire B, is also laid on the tabletop oriented north-south. Which of the following statements is true? ( If Wire B carries no current in it and lies to the left (west) of wire A, then it will experience an attractive force to the right (towards wire A). (11) If Wire B carries a northward conventional current and lies to the left (West) of wire A, then it will experience an attractive force to the right (towards Wire A). (II) If Wire B carries a northward conventional current and lies to the right (east) of wire A, then it will experience a repulsive force to the right (away from Wire A). (iv) If Wire B carries a southward conventional current and lies to the left (west) of wire A, then it will experience a repulsive force to the left (away from Wire A).

Answer 1

Consider a wire conrying consent I, so are to Amper's line magnetic field can be given as s distance from here force the second whe f = I2 ALB But there is no cassent, I 2 = 0 carrying current on 24 both wires are same clirection, they will attrect each other while if they are carrying current in opposite clirections, will repel each other. only in ard in and sight.
