A concave mirror produces a magnified image when the object is placed in front of the mirror:
(i) between its pole and focus
(ii) between the focus and centre of curvature
In case (i) the image is virtual and erect, whereas in case (ii) the image is real and inverted.

A concave mirror forms a magnified image of an object when

Case – 1: Object is between centre of curvature (C) and principal focus (F) of the mirror.

Case – 2: Object is between principle focus (F) and pole (P) of the mirror.

Difference:

In first case the image is real and inverted while in case-2, the image would be virtual and erect.
