<p>Oops, I made the same mistake. Didn’t even realize there was a box</p>
<p>And for E&M3a, it’s counterclockwise because the current int he wire produces a B field out of the page through the loop that is decreasing because I=I0 - Kt is a decreasing function. Thus, magnetic flux through the loop is decreasing. Lenz’ law tells us that current in the loop will oppose this change in flux - namely that a B field will be produced out of the page by the current in order to combat the decreasing flux.</p>
