I have 3 more physics electromagnetism problems, thanks again for the help (helped tremendously in the last unit for my test).

not sure what equation to use, i can solve for change in flux using the magnetic field and area, but not sure how to get induced emf (which would help me get current)

how do i get the direction of the acceleration?

not sure what to do here, i thought you use lenz's law where it creates a counter b field against the motion of the bar magnet, but that doesn't work for the bottom.
thanks again!
