Based on the collective response of Arrott plots and {\\Delta}SM (T), a magnetic phase diagram of CaMn7O12 is suggested. A new magnetic transition at TN3 ~20 K where the system changes from noncollinear AFM to collinear AFM is reported. An anomaly observed in both {\\Delta}SM (T) and Arrott plots around 64 K has been attributed to high external field induced spin canting leading to change in magnetic order inducing phase transition.
