Let's determine what can exert force over a distance because the magnet is surrounded by a magnetic field.
The force exerted by a magnet on certain materials can be called the magnetic force.
The force is exerted over distances and includes forces of attraction and repulsion.
A magnet is an object which produces a magnetic field.
Hence, a magnet can exert force over a distance because the magnet is surrounded by a magnetic field.
ANSWER:
Magnet
