C Chegg -Get x bis/viewphp?id-4804354 Jump to... pling Learning | The magnitude of the magnetic field produced by a long straight wire is proportional to the current passing through the wire and inversely proportional to the distance from the wire. Consider the five pairs of long parallel wires shown below. The arrows indicate the direction of the current in each wire, with small arrows each pair, determine in which one of the a current of 3 A and large arrows representing a current of 9 A. For ng regions the net magnetic field is zero someplace: on the left of both wires between the two wires on the right of both wires none of the above (i.e. nowhere) Do not consider distances very far from the wires since in this case the magnetic field always goes to zero. A) Left (8) (B) Between (C) Right (D)N O Previous e Check Answor Next Hint Exit

Explanation / Answer

1st combination:

currents are in opposire direction so zero field point will not be inbetween the wire.

magnitude of current is same so distance of that point have to be same from both wires.

these two situation is not possible together.

Ans: NoWhere

2nd combination:

opposite direction so either to the left Or to the right.

and it will be near to small magnitude current.

Ans: Left

3rd: currents are in same direction.

Ans: In between

4th: opposite direction.

smaller current is in right wire.

so Ans: Right

5th: same directon current.

ANs: Inbetween
