I figured out how to do the first couple questions using Lenz Law after a lot of reading. However, I still don't know how to relate magnetic force to a circular loop. I get that for A and B, the magnetic field lines are pointing in the loop while for C and D, the field lines are pointing away...

Homework Equations
I am not really good at this topic, but I think you would need both the right hand rules (one that involves finding direction of current via magnetic field as well as the one for finding magnetic force)
The Attempt at a Solution
So I drew out magnetic...
From what I understand, magnetic flux is equal to B * A, where B is the magnetic field that is perpendicular to the surface, and A is the surface area. Does this mean the change in magnetic flux between the two halves of D causes magnetic flux to decrease?
Thanks for the welcome! Isn't the magnetic field constant throughout, meaning the magnetic flux is constant? Or does magnetic flux decreases along the X axis even though magnetic field is constant?
Homework Statement
I have attached a picture that details the problem. This is my practice test and I have no clue what I am doing wrong. Essentially a loop of wire is moving in constant velocity into a magnetic field. The magnetic field lines are pointing into the page. The problem is...
