Homework Statement
I don't understand why the answer in this problem is choice A.
http://grephysics.net/ans/9277/57
I'm confused.
Lets say the semi circle is FULLY outside of the circle. For awhile after that, the semi circle would be accelerating the rate at which a certain % of it is inside the magnetic field.. So the change in magnetic flux with respect to time increases it's rate for awhile, and I don't feel that's reflected in choice A. Anyone help me out?
