How Does a Changing Current in One Wire Affect the Current in an Adjacent Wire?

Click For Summary
SUMMARY

The discussion centers on the interaction between two parallel wires, specifically how an increasing current in one wire affects the current in an adjacent wire. The Right Hand Rule is applied to determine the direction of the magnetic field generated by the left wire, which influences the adjacent wire. The principles of Lenz's Law and Faraday's Law are crucial for understanding how a changing magnetic field can induce a current in a nearby wire. The assumption that both wires are infinite and straight is valid for this analysis.

Homework Statement



So basically there are two parallel wires

the wire on the left has an increasing current going north.
What would be the direction of the current in the wire left of it?


Homework Equations



Right Hand Rules

The Attempt at a Solution



So I'm really not sure how an increasing or decreasing current affects wires around it. But I'm guessing that right next to the left wire the magnetic field lines are going in.

So am I correct to be assuming that both wires are infinite and straight?

If such is the case, ask yourself if a changing magnetic field (which the time dependent current hints at) would be able to induce a current in a nearby infinite straight wire. Check out Lenz's Law and Faraday's Law for a simple "why does a changing magnetic field induce a current" answer and then apply what you get from those to this problem.
