Homework Statement
A metal loop is attached to an axle with a handle as shown. The north pole of a magnet is placed below the loop and the handle turned so that the loop rotates counterclockwise at a constant angular speed.
On the two diagrams below, indicate the direction of the induced current in the loop at each of the instants shown. If the current is zero, state that explicitly. Explain how you determined your answers.
Homework Equations
none
The Attempt at a Solution
On the first instant, I was thinking that maybe the induced current is zero because there's no flux through the loop? I'm completely not sure though. For the second instant, I'm pretty sure there is a current, but I don't know about the direction. Would it be clockwise around the loop? Since the current is trying to counteract the increasing flux? I don't know if that's true.
I am not confident in any of my answers, so any help is appreciated!
