Question

this pushing force occurs when like (same) poles of two magnets interact: repulsion
state when most of the magnetic domains are lined up in the same direction:
a pulling force, such as when the opposite poles of two magnets interact: attraction
a type of non - contact force that can be either attractive or repulsive:
a representation of magnetic forces around a magnet:

Explanation:

1. When magnetic domains align uniformly, the material acts as a magnet (magnetized state).
2. Magnetism is a non-contact force that shows both attraction and repulsion between magnets.
3. Magnetic field lines are the standard way to map the magnetic force distribution around a magnet.

Answer:

State when most of the magnetic domains are lined up in the same direction: magnetized (or magnetic saturation)
A type of non-contact force that can be either attractive or repulsive: magnetism
A representation of magnetic forces around a magnet: magnetic field lines
