Human Factors; Procedure
My student and I were practicing commercial pilot maneuvers in the South Practice Area of the ZZZ terminal area. We were .5 NM SE of [the lake] doing a steep spiral from 4;500 feet down. We made multiple radio calls and this was our second maneuver. After the first turn and a half; we were alerted to a traffic conflict on my iPad; which was supplied by a Sentry Mini ADS-B receiver. We looked for the traffic and spotted them on a collision course. We immediately terminated the maneuver and I took controls from the student to execute an emergency climb; as our paths were roughly perpendicular and I did not believe a turn would be enough to clear us. The other aircraft (C172) passed directly under us without making a control input or diverting course. We did some more maneuvers; also with thorough radio calls but had no further conflicts.
Flight Instructor reported taking evasive action due to a Near Mid Air Collision.
