What is the motor effect?

When a current-carrying wire is placed between magnetic poles and the magnet and wire exert a force onto each other. This causes the wire to move.

The induction of potential difference in a wire which is moving relative to a magnetic field.

How can you increase the turning effect?

ensure that the wire is perpendicular to the magnetic field

move it further from the magnet
