Hey guys,
I have a simple conceptual question: Let's say I'm moving a loop of wire into a constant magnetic field that points into the page. The wire needs to create a magnetic field out of the page to oppose this previous change in flux. The typical question would be which direction does the current flow? I know about the right hand rule where you wrap your hand around the wire and let thumb point in the direction of the current. But the magnetic field created by a wire is such that it wraps around the wire, so I am not sure from which side i have to wrap my hands around the loop to represent the field created?
An example of an answer to clarify my question (just guessing btw): the direction of the magnetic field created to oppose the change in flux is represented by the direction your fingers point on the INSIDE of the loop.
Thanks in advance for your efforts.
