It's called hovering. It works like this:
An aeroplane msut keep moving to stay upa s it generates lift by moving air over tis wings, which pushes htat air down.
A helicopter's rotor pushes the air directly down, so it can stay put. To move around, it angles the rotor slightly to change hte direction fo flow.

I would call it hovering...don't know if there's a more proper or technical term...
As an aircraft, the primary advantages of the helicopter are due to the rotor blades that revolve through the air, providing lift without requiring the aircraft to move forward the way an airplane does. This creates the ability for the helicopter to take off and land vertically without the need for runways.

Hovering is the manuver. The rotors are shaped to produce lift. The helicopter's rotor assembly is manipulated to counter wind effects so that the pilot can hold the aircraft steady.

it's called hovering.
it's stays put because the amount of lift the blades generate it equal to the force of gravity on the helicopter.
