The Attempt at a Solution
I found dB/dr to be constant near r = 0, so it's a straight line, implying B increases linearly with r near r = 0.
For the second part, I assume the setup is as such, if not placing the dipole with its axis parallel to the coil would make B = 0, and hence no force at all..Not sure what energy has to do in this case.
