Electromagnetic Induction (Long straight wire above circulua

Click For Summary
SUMMARY

The discussion centers on the phenomenon of electromagnetic induction, specifically regarding a circular loop of wire placed next to a long straight wire with an increasing current (I). The induced current in the circular loop is determined to be clockwise. This conclusion is reached through the application of Lenz's Law, which states that the induced electromotive force (EMF) will act to oppose the change in magnetic flux. The right-hand rule is utilized to visualize the direction of the magnetic field and the resulting induced current.

Homework Statement


A circular loop of wire is placed next to a long straight wire. The current I in the long straight wire is increasing. What direction is the current that's induced in the circular loop?

The Attempt at a Solution


I'm aware that the answer is clockwise; however, I'm trying to conceptualize exactly how. I'm quite familiar with induction using Faraday's Law when it comes to magnetic fields. I know that the current will create a magnetic field; however, my brain must not be working today as I'm not able to combine these concepts at the moment. Can someone please break this relatively simply question down for me in a way that helps me to grasp the concept?

Thanks!

Disregard; I think I answered my own question; Lenz's Law states that the induced EMF (and thus, current) would act in such a way to counter the motion of the current in the wire. Based on the right-hand rule, the magnetic field lines around the straight wire would be clockwise, meaning the opposing magnetic field lines around the loop would be counterclockwise. With the right-hand rule, this shows that the induced EMF's direction would be clockwise around the loop (and thus, making the current counterclockwise).

(I was going to delete but I don't see an option to do so).
