Strategy:
 Maximum attraction to a magnetic field corresponds to the highest degree of paramagnetism (i.e., the maximum number of unpaired electrons).

Step 1: Calculate unpaired electrons ()
- :  () in octahedral field  2 unpaired.
- :  () with strong field en  low-spin ()  0 unpaired.
- :  ()  0 unpaired.
- :  () with weak field  high-spin ()  3 unpaired.

Step 2: Identify the maximum
 has the most unpaired electrons (3).
